This sounds interesting, what do we get if we go this route? Does it
make certain things easier/faster/more portable?

Good idea! I think that we could make stuff work at the PIR level
going that route, but I don't think HLL's would work using that
method. But it gives us a path forward, which is very good. I still
think that Parrot_ext_call_cb is going to be the way to get HLL
argument passing working correctly, perhaps wrapped in some kind of
container PMC.
