Class::MOP::Method - Method Meta Object
-=head1 SYNOPSIS
-
- # ... more to come later maybe
-
=head1 DESCRIPTION
-The Method Protocol is very small, since methods in Perl 5 are just
-subroutines within the particular package. Basically all we do is to
-bless the subroutine.
-
-Currently this package is largely unused. Future plans are to provide
-some very simple introspection methods for the methods themselves.
-Suggestions for this are welcome.
