Ugh. > The MM dispatch problem is pretty much solidly in > the realm of pmc inheritance, There _is_ no pmc inheritance right now.

Not really. There is only one "base class". Also, you're not inheriting a data structure or member variables. All you "inherit" (which actually happens at compilation of the PMC) are "member functions". If you happen to use your data differently than default.pmc then these functions are no longer valid. If any of this is to change then I haven't heard of it. - D <[EMAIL PROTECTED]>
