Maybe allow something of the sort

static assert(arity!fun(int) == 1);
static assert(arity!gun(int, int) == 2);

?

I had reported this as a Phobos issue (see above), but since it has been marked
as a duplicate for a dmd one, there's not much I can do. Compiler stuff is
still magic to me, I'm afraid.
