I'd prefer that we do this now. Leaving the problem to lurk for
future maintainers to deal with it would mean maintenance burden
and/or subtle bugs waiting to bite.
Emacs is a large and complex program, with many areas of its code
understandable only by a tiny few, sometimes by a single individual.
Leaving such dark corners means trading somebody else's future efforts
for our current convenience. I just spent the best part of my weekend
hunting `int's that should have been EMACS_INT's (which, btw, is the
only _real_ problem with overflow that I know about), and I would hate
to leave similar problems to those who will come after us.
