I have a number of cases (filter, map, reduce), where I am passed an arbirary sub and need to call it. I should not have to know how the sub is implemented.
I'd a look at map and friends now. You are running code that has a signature of "PP". You'd need additionally:
if (func->vtable->base_type == enum_class_NCI) {
typedef PMC* (*func_pp)(Interp*, PMC*);
func_pp cfunc = (func_pp) D2FPTR(PMC_struct_val(func));
item = (cfunc)(interpreter, item);
}
else { ...You could of course add a general "call_PP" wrapper that handles both cases. But as you did already replace the general runops_args with a hand-crafted call setup, adding above lines should do it.
