It can be done any which way but loose, and I'm trying to keep my thinking
flexible for any applied use in this sense. What I'm _doing_ for my own
work at this point is simply making a creole filter (or source filter),
and spitting out perl5 which is then sucked into eval_pv(). For this, I'd

On a related note: a wrapper not completely unlike

void *vp;
int (*dummy)(void) *fp;

Yes, and we are in danger of "premature optimization" of the _interface_.
What we need to start with is a list of "what we need to know" - they may
as well be separate parameters at this point - the

possible, I would like to work closely to data
