struct Parrot_sub *new_closure(Interp *interp): Returns a new Parrot_sub with its own sctatchpad.; XXX: Need to document semantics in detail.
struct Parrot_cont *new_continuation(Interp *interp, struct Parrot_cont *to): Returns a new Parrot_cont to the context of to with its own copy of the current interpreter context.
struct Parrot_cont *new_ret_continuation(Interp *interp): Returns a new Parrot_cont pointing to the current context.
struct Parrot_coro *new_coroutine(Interp *interp): Returns a new Parrot_coro.; XXX: Need to document semantics in detail.
PMC *new_ret_continuation_pmc(Interp *interp, opcode_t *address): Returns a new RetContinuation PMC. Uses one from the cache, if possible; otherwise, creates a new one.
void invalidate_retc_context(Interp *, PMC *cont): Make true Continuation from all RetContinuations up the call chain.
Parrot_full_sub_name: Print name and location of subroutine, This should finally use the label name of the frozen Sub PMC image for now locate the Sub name in the globals.
