This is not a Python vs Ruby debate, it's a comparison of features for the
sole purpose of knowing better what would need to be in a multi-language
VM to support Ruby.

That's way too sort-of to be called "mixins" and AFAIK offers no advantage
over Perl's multiple inheritance. Am I right ?

Anyway the issue is, in a Perl/Python/Ruby VM, mixins with Ruby-style
inheritance is required, and so we'd have to make sure Damian's NEXT
proposal goes through.
