yes, you are correct. i agree that a warning is the best solution. and
it would be perfectly ok (imho) to turn off the warning by a
compiler directive (thus not having to change the code).

but i sure would like that warning, please.

talking about warnings i would like the current erlc system (warnings
if the right compiler switch is on) changed to its opposite:
warnings, unless the right switch turns them off.
rationale: experienced programmers that want to break the rules can
turn warnings off. new programmers that need all the help they can get,
do not know enought to turn the warnings on.
