Yeah, through composition or inheritance. Manually stuffing a code PMC
into a class won't give you conflict checking, and won't set up the
necessary lookup tables for a method/vtable.
If you really want to pretend you're working with GLOBs, though, you can
introspect into the source class to retrieve the method/vtable code
object, and call add_method on the destination class to have it store
the retrieved code object.
