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.
+The Method Protocol is very small, since methods in Perl 5 are just
+subroutines within the particular package. We provide a very basic
+introspection interface.
=head1 METHODS
=item B<meta>
-This will return a B<Class::MOP::Class> instance which is related
+This will return a B<Class::MOP::Class> instance which is related
to this class.
=back
=over 4
-=item B<wrap (&code)>
+=item B<wrap ($code, %params)>
-This simply blesses the C<&code> reference passed to it.
+This is the basic constructor, it returns a B<Class::MOP::Method>
+instance which wraps the given C<$code> reference. You can also
+set the C<package_name> and C<name> attributes using the C<%params>.
+If these are not set, then thier accessors will attempt to figure
+it out using the C<Class::MOP::get_code_info> function.
-=item B<wrap>
+=item B<clone (%params)>
-This wraps an existing method so that it can handle method modifiers.
+This will make a copy of the object, allowing you to override
+any values by stuffing them in C<%params>.
=back
=over 4
-=item B<name>
+=item B<body>
-=item B<package_name>
+This returns the actual CODE reference of the particular instance.
-=back
+=item B<name>
-=head2 Modifiers
+This returns the name of the CODE reference.
-=over 4
+=item B<package_name>
-=item B<add_before_modifier ($code)>
+This returns the package name that the CODE reference is attached to.
-=item B<add_after_modifier ($code)>
+=item B<fully_qualified_name>
-=item B<add_around_modifier ($code)>
+This returns the fully qualified name of the CODE reference.
