There are only two reasons I can think of: either to raise awareness of the
FIXME comment :) or because this code was originally only intended for numeric
inquiry functions, as their value can always be evaluated at compile time.
But since we also allow array inquiry functions (lbound etc.), I think this is
ok, once you update the comment further down in check_inquiry.
