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.
+subroutines within the particular package. We provide a very basic
+introspection interface.
=head1 METHODS
=over 4
-=item B<new (&code)>
+=item B<wrap ($code)>
-This simply blesses the C<&code> reference passed to it.
+This is the basic constructor, it returns a B<Class::MOP::Method>
+instance which wraps the given C<$code> reference.
=back
=over 4
+=item B<body>
+
+This returns the actual CODE reference of the particular instance.
+
=item B<name>
+This returns the name of the CODE reference.
+
=item B<package_name>
-=back
+This returns the package name that the CODE reference is attached to.
-=head1 SEE ALSO
+=item B<fully_qualified_name>
-http://dirtsimple.org/2005/01/clos-style-method-combination-for.html
+This returns the fully qualified name of the CODE reference.
