I think producing pointless warnings also gives Python a bad name
(I've seen many complaints about Python's warnings in the past, in
  particular when they fill up Apache log files).

However, if everybody (and here I mean everybody) can agree that adding
a warning to the current implementation would be an acceptable
compromise, I could agree to such a compromise also (although I
would prefer if somebody else took the blame for adding that warning.
I happily take the blame for changing the behavior).

What specific warning would you propose, and in what specific
circumstance would it be issued?
