Unless my reading of the Ada 95 standard is wrong, there's nothing
that precludes functions having side effects. The only thing an Ada
function cannot do is having "out" or "in out" parameters, so it
cannot modify its arguments, and even that can be circumvented (as
you can pass "in" access parameters).
