There's going to be a new op. Looks like:
new Px, iy
Creates a new PMC in register X, of type Y. Allocates a new PMC pointer,
so if there's something in X already the pointer's overwritten. (Hopefully
it's been saved or it'll be GC'd later)
To start, the guaranteed PMC types are:
< 0 : Reserved to the interpreter (sync objects and such)
0 : undef
1 : Perl scalar
2 : Perl array
3 : Perl hash
4 : Perl list
and the rest'll have to be looked up by name from the big hash 'o loaded
PMC types. When we have one. :)
Anyone care to take a shot at the PMC versions of all the standard opcodes
while we're at it?
