The best way to deal with this is to have some kind of knob you can turn
to enable or disable warnings about these sorts of things. Could be a
command-line flag, a stand-alone tool (i.e. pylint), or even something
in-line (like perl' 'use strict' directive).
Good engineering practice would be use enable "debug mode" during
testing and review all the warnings to see which ones surprise you.
