Hadn't considered it, but my first thought is to not shoot for that as a
target. The code that takes the parameters from the C-level calling frame
and builds PMCs out of them will be operating at a very low level, with
deep carnal knowledge of a platform/processor pair's calling sequence. It's
going to have to know the order that things go in registers, which
registers hold which types of parameters, and how excess parameters flow on
to the stack (or wherever they go) This is code that'll be different
(potentially) for every operating system on every processor perl runs (and
supports this) and I don't know that we can get this flexible. 'Specially
since many of the conversion routines will have to be written in C, rather
than in perl. (If perl gets a pointer to an array of char pointers, what
exactly could it do with it?)
Having said that, if we manage to make it happen then I'm all for it. :)
