Ah, perl 5 SVs. Exactly what I was trying to avoid. :)

Couple of things:
*) Use the cache entry in the PMC header. It'll mean for ints and floats
you won't need to bother with a separate structure or dereference
*) Swap out vtables as the pmc internals change, rather than vectoring off
flags.
Yeah, some of the code will be a little grotty, but not as bad as you might
think.
