Yes, there's a PMC inheritance mechanism that works for things that wouldn't be called "classes" in Perl 6. For example, PerlUndef is a PMC that's derived from PerlInt.

I think so, though I imagine it would be a bit of work to make sure the ParrotObjects were actually complying 100% with the API provided by the current PMCs. I can imagine that for debugging purposes -- or maybe just for the sheer fun of it -- someone will eventually try it. -- Chip Salzenberg <[EMAIL PROTECTED]>
