void mark_context(Interp *interpreter, parrot_context_t *ctx): Marks the context *ctx.
struct Parrot_sub *new_sub(Interp *interp): Returns a new Parrot_sub.
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. If to is NULL, then the to_ctx is set to the current 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.
PMC *Parrot_find_pad(Interp*, STRING *lex_name): Locate the LexPad containing the given name. Return NULL on failure.
