Well, damn. And I mean that sincerely. :(

Stacks cost time and programmer effort. Parameters are generally passed in
registers, (how many depends on your architecture, but sane ones have a
bunch) while stacks require smacking data into memory somewhere and messing
with the stack pointer. Even if you have a macro to push, it means doing this:
PUSH(i);
PUSH(j);
PUSH(k);
call_foo();
instead of:
call_foo(i, j, k);
Stacks are OK for internal work (though I'd prefer a register file, if even
a virtual one) but for externally exposed stuff we're better off taking
parameters if we can.
