But I think you meant "on a > *particular* class [metaclass] instance", am I right?
Yes, I believe this is a better phrasing. If I want to define a new method or or override an existing method on a metaclass instance [a class], then how do I do that? The particular instance I'm looking at is a C<Str> class for Perl 6, where I want the get_string vtable function for the C<Str> metaclass instance is different from get_string of a C<Str> class object. At the moment perl6 is handling this (in PMC classes) by checking the identify of the invocant when get_string is executed and then responding appropriately. But I'm thinking it's likely that C<Str> will be implemented using pdd15 objects, so I'm looking for the "preferred approach" for doing things like this. Thanks, Pm
