Well, all real variables in use will be PMCs, and symbol table
management is built in to Parrot. ([INS] registers are just used to
avoid the indirections of a PMC's vtable and make some operations
faster.) There's an opcode like:
find_global Px, "name"
which fetches the global variable "name" and puts it into Px, and a
similar one for lexicals.
