+=head1 NAME
+
+Class::MakeMethods::Composite::Array - Basic array methods
+
+=head1 SYNOPSIS
+
+  package MyObject;
+  use Class::MakeMethods::Composite::Array (
+    new => 'new',
+    scalar => [ 'foo', 'bar' ],
+    array => 'my_list',
+    hash => 'my_index',
+  );
+  ...
+  
+  my $obj = MyObject->new( foo => 'Foozle' );
+  print $obj->foo();
+  
+  $obj->bar('Barbados');
+  print $obj->bar();
+  
+  $obj->my_list(0 => 'Foozle', 1 => 'Bang!');
+  print $obj->my_list(1);
+  
+  $obj->my_index('broccoli' => 'Blah!', 'foo' => 'Fiddle');
+  print $obj->my_index('foo');
+
+=head1 DESCRIPTION
+
+The Composite::Array suclass of MakeMethods provides a basic
+constructor and accessors for blessed-array object instances.
+
+=head2 Class::MakeMethods Calling Conventions
+
+When you C<use> this package, the method declarations you provide
+as arguments cause subroutines to be generated and installed in
+your module.
+
+You can also omit the arguments to C<use> and instead make methods
+at runtime by passing the declarations to a subsequent call to
+C<make()>.
+
+You may include any number of declarations in each call to C<use>
+or C<make()>. If methods with the same name already exist, earlier
+calls to C<use> or C<make()> win over later ones, but within each
+call, later declarations superceed earlier ones.
+
+You can install methods in a different package by passing C<-TargetClass =E<gt> I<package>> as your first arguments to C<use> or C<make>. 
+
+See L<Class::MakeMethods> for more details.
+
+=head2 Class::MakeMethods::Basic Declaration Syntax
+
+The following types of Basic declarations are supported:
+
+=over 4
+
+=item *
+
+I<generator_type> => "I<method_name>"
+
+=item *
+
+I<generator_type> => "I<name_1> I<name_2>..."
+
+=item *
+
+I<generator_type> => [ "I<name_1>", "I<name_2>", ...]
+
+=back
+
+See the "METHOD GENERATOR TYPES" section below for a list of the supported values of I<generator_type>.
+
+For each method name you provide, a subroutine of the indicated
+type will be generated and installed under that name in your module.
+
+Method names should start with a letter, followed by zero or more
+letters, numbers, or underscores.
+
+=head2 Class::MakeMethods::Composite Declaration Syntax
+
+The Composite syntax also provides several ways to optionally
+associate a hash of additional parameters with a given method
+name. 
+
+=over 4
+
+=item *
+
+I<generator_type> => [ "I<name_1>" => { I<param>=>I<value>... }, ... ]
+
+A hash of parameters to use just for this method name. 
+
+(Note: to prevent confusion with self-contained definition hashes,
+described below, parameter hashes following a method name must not
+contain the key 'name'.)
+
+=item *
+
+I<generator_type> => [ [ "I<name_1>", "I<name_2>", ... ] => { I<param>=>I<value>... } ]
+
+Each of these method names gets a copy of the same set of parameters.
+
+=item *
+
+I<generator_type> => [ { "name"=>"I<name_1>", I<param>=>I<value>... }, ... ]
+
+By including the reserved parameter C<name>, you create a self
+contained declaration with that name and any associated hash values.
+
+=back
+
+Basic declarations, as described above, are treated as having an empty parameter hash.

+
+=head2 Positional Accessors and %FIELDS
+
+Each accessor method is assigned the next available array index at
+which to store its value.
+
+The mapping between method names and array positions is stored in
+a hash named %FIELDS in the declaring package. When a package
+declares its first positional accessor, its %FIELDS are initialized
+by searching its inheritance tree.
+
+B<Warning>: Subclassing packages that use positional accessors is
+somewhat fragile, since you may end up with two distinct methods assigned to the same position. Specific cases to avoid are:
+
+=over 4
+
+=item *
+
+If you inherit from more than one class with positional accessors,
+the positions used by the two sets of methods will overlap.
+
+=item *
+
+If your superclass adds additional positional accessors after you
+declare your first, they will overlap yours.

+
+
+=head1 DESCRIPTION
+
+The Composite::Global suclass of MakeMethods provides basic accessors for shared data.
+
+=head2 Class::MakeMethods Calling Interface
+
+When you C<use> this package, the method declarations you provide
+as arguments cause subroutines to be generated and installed in
+your module.
+
+You can also omit the arguments to C<use> and instead make methods
+at runtime by passing the declarations to a subsequent call to
+C<make()>.
+
+You may include any number of declarations in each call to C<use>
+or C<make()>. If methods with the same name already exist, earlier
+calls to C<use> or C<make()> win over later ones, but within each
+call, later declarations superceed earlier ones.
+
+You can install methods in a different package by passing C<-TargetClass =E<gt> I<package>> as your first arguments to C<use> or C<make>. 
+
+See L<Class::MakeMethods> for more details.
+
+=head2 Class::MakeMethods::Basic Declaration Syntax
+
+The following types of Basic declarations are supported:
+
+=over 4
+
+=item *
+
+I<generator_type> => "I<method_name>"
+
+=item *
+
+I<generator_type> => "I<name_1> I<name_2>..."
+
+=item *
+
+I<generator_type> => [ "I<name_1>", "I<name_2>", ...]
+
+=back
+
+See the "METHOD GENERATOR TYPES" section below for a list of the supported values of I<generator_type>.
+
+For each method name you provide, a subroutine of the indicated
+type will be generated and installed under that name in your module.
+
+Method names should start with a letter, followed by zero or more
+letters, numbers, or underscores.
+
+=head2 Class::MakeMethods::Composite Declaration Syntax
+
+The Composite syntax also provides several ways to optionally
+associate a hash of additional parameters with a given method
+name. 
+
+=over 4
+
+=item *
+
+I<generator_type> => [ "I<name_1>" => { I<param>=>I<value>... }, ... ]
+
+A hash of parameters to use just for this method name. 
+
+(Note: to prevent confusion with self-contained definition hashes,
+described below, parameter hashes following a method name must not
+contain the key 'name'.)
+
+=item *
+
+I<generator_type> => [ [ "I<name_1>", "I<name_2>", ... ] => { I<param>=>I<value>... } ]
+
+Each of these method names gets a copy of the same set of parameters.
+
+=item *
+
+I<generator_type> => [ { "name"=>"I<name_1>", I<param>=>I<value>... }, ... ]
+
+By including the reserved parameter C<name>, you create a self-contained declaration with that name and any associated hash values.

If the global value was previously undefined, a new array is autovivified. The current value in each position will be overwritten, and later arguments with the same index will override earlier ones. Returns the current array-ref value.
+
+=item *
+
+If called with a list of argument pairs, each with the first item being a reference to an array of up to two numbers, loops over each pair and uses those numbers to splice the value array. 
+
+The first controlling number is the position at which the splice will begin. Zero will start before the first item in the list. Negative numbers count backwards from the end of the array. 
+
+The second number is the number of items to be removed from the list. If it is omitted, or undefined, or zero, no items are removed. If it is a positive integer, that many items will be returned.
+
+If both numbers are omitted, or are both undefined, they default to containing the entire value array.
+
+If the second argument is undef, no values will be inserted; if it is a non-reference value, that one value will be inserted; if it is an array-ref, its values will be copied.
+
+The method returns the items that removed from the array, if any.

+=head1 DESCRIPTION
+
+The MakeMethods subclass provides accessor methods that search an inheritance tree to find a value. This allows you to set a shared or default value for a given class, optionally override it in a subclass, and then optionally override it on a per-instance basis. 
+
+Note that all MakeMethods methods are inheritable, in the sense that they work as expected for subclasses. These methods are different in that the I<data> accessed by each method can be inherited or overridden in each subclass or instance. See L< Class::MakeMethods::Utility::Inheritable> for more about this type of "inheritable" or overridable" data.
+
+
+=head2 Class::MakeMethods Calling Interface
+
+When you C<use> this package, the method declarations you provide
+as arguments cause subroutines to be generated and installed in
+your module.
+
+See L<Class::MakeMethods::Standard/"Calling Conventions"> for more information.
+
+=head2 Class::MakeMethods::Standard Declaration Syntax
+
+To declare methods, pass in pairs of a method-type name followed
+by one or more method names. 
+
+See the "METHOD GENERATOR TYPES" section below for a list of the supported values of I<generator_type>.
+
+See L<Class::MakeMethods::Standard/"Declaration Syntax"> and L<Class::MakeMethods::Standard/"Parameter Syntax"> for more information.

+=head2 scalar - Overrideable Accessor
+
+For each method name passed, uses a closure to generate a subroutine with the following characteristics:
+

+
+=item *
+
+May be called as a class or instance method, on the declaring class or any subclass. 
+
+=item *
+
+If called without any arguments returns the current value for the callee. If the callee has not had a value defined for this method, searches up from instance to class, and from class to superclass, until a callee with a value is located.
+
+=item *
+
+If called with an argument, stores that as the value associated with the callee, whether instance or class, and returns it, 
+
+=item * 
+
+If called with multiple arguments, stores a reference to a new array with those arguments as contents, and returns that array reference.

+
+For each method name passed, uses a closure to generate a subroutine with the following characteristics:
+
+=over 4
+
+=item *
+
+May be called as a class method, or on any instance or subclass, Must be called on a hash-based instance.
+
+=item * 
+
+The class value will be a reference to an array (or undef).
+
+=item *
+
+If called without any arguments, returns the current array-ref value (or undef).
+
+
+=item *
+
+If called with a single non-ref argument, uses that argument as an index to retrieve from the referenced array, and returns that value (or undef).
+
+=item *
+
+If called with a single array ref argument, uses that list to return a slice of the referenced array.
+
+=item *
+
+If called with a list of argument pairs, each with a non-ref index and an associated value, stores the value at the given index in the referenced array. If the class value was previously undefined, a new array is autovivified. The current value in each position will be overwritten, and later arguments with the same index will override earlier ones. Returns the current array-ref value.
+
+=item *
+
+If called with a list of argument pairs, each with the first item being a reference to an array of up to two numbers, loops over each pair and uses those numbers to splice the value array. 
+
+The first controlling number is the position at which the splice will begin. Zero will start before the first item in the list. Negative numbers count backwards from the end of the array. 
+
+The second number is the number of items to be removed from the list. If it is omitted, or undefined, or zero, no items are removed. If it is a positive integer, that many items will be returned.
+
+If both numbers are omitted, or are both undefined, they default to containing the entire value array.
+
+If the second argument is undef, no values will be inserted; if it is a non-reference value, that one value will be inserted; if it is an array-ref, its values will be copied.
+
+The method returns the items that removed from the array, if any.

+  }
+  
+  Class::MakeMethods::Composite::Universal->make(

+
+A convenient wrapper for C<make()> and the C<patch> method generator.
