No, I can't see that happening unfortunately. It'd require the caller to
know whether it was calling a coroutine or normal sub.
OTOH, you *could* have the PMC for the coroutine be appropriately magic,
such that when you fetched it out of the symbol table you didn't get the
single shared sub PMC, but rather a custom PMC that had the setup
information in it that cached whatever was needed such that repeated
invocations had access to previously stored information...
