 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.
+The Method Protocol is very small, since methods in Perl 5 are just

+=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.

+
+This returns the name of the CODE reference.

+
+The metaclass of the method
