To remove the emulation aliasing, call +C<use Class::MakeMethods::Emulator::mcoder '-release_namespace'>. +The same mechanism is also available for the "sugar" subclasses. + +B<Caution:> This affects B<all> subsequent uses of the mcoder module in +your program, including those in other modules, and might cause +unexpected effects. + + +=head1 SEE ALSO + +See L<Class::MakeMethods> for general information about this distribution. + +See L<Class::MakeMethods::Emulator> for more about this family of subclasses. + +See L< mcoder> for documentation of the original module. + +=cut |
