[Python-Dev] Re: A warning switch?

Fredrik Lundh writes ( about .append(x,y) ):

I suggest adding an explicit warning in the 1.6 docs, and removing it in the first post-1.6 release.

What about adding a command-line switch for enabling warnings, as has been suggested long ago? The .append() change could then print a warning in 1.6alphas (and betas?), but still run, and be turned into an error later. -- A.M.
