Class::MOP::Method - Method Meta Object
-=head1 SYNOPSIS

=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 and provide some very simple introspection
-methods for it.

+=item B<wrap ($code, %params)>
+
+This is the basic constructor, it returns a B<Class::MOP::Method>
+instance which wraps the given C<$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<clone (%params)>
+
+This will make a copy of the object, allowing you to override
+any values by stuffing them in C<%params>.

+
+=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<associated_metaclass>
+
+The metaclass of the method
+
+=item B<package_name>
+
+This returns the package name that the CODE reference is attached to.
+
+=item B<fully_qualified_name>
+
+This returns the fully qualified name of the CODE reference.
+
+=item B<original_method>
+
+If this method object was created as a clone of some other method
+object, this returns the object that was cloned.
+
+=item B<original_name>
+
+This returns the original name of the CODE reference, wherever it was
+first defined.
+
+=item B<original_package_name>
+
+This returns the original package name that the CODE reference is
+attached to, wherever it was first defined.
+
+=item B<original_fully_qualified_name>
+
+This returns the original fully qualified name of the CODE reference,
+wherever it was first defined.
