I've seen it used a couple times for timestamps, though that was in
C/C++.  e.g.

now = time(NULL);
then = now - 86400;

The idea of rejecting ? because it's too C-like just seems silly,
though.  It's already been used in another language, therefore it's
necessarily bad?  I can understand the objection that using
punctuation in this case is too cryptic, but of the available
punctuation, ? makes the most sense IMO, and it's not already used in
python.
