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.
