We could say "expression compilation" and it'd still be valid. Or just
drop the last four words altogether. I don't think we want to expend the
verbiage to be more precise here, since it's only a tangential point.
BTW, while looking at this I noted that copyfuncs.c has a
check_stack_depth call but outfuncs, readfuncs, equalfuncs don't.
Surely that's not good.
