my point was that most Python programmers won't
see that notification. when these people download
1.6 final and find that all theirs apps just broke, they
probably won't be happy with a pointer to dejanews.

this rather common pydiom:
append =3D list.append
for x in something:
it's used a lot where performance matters.

yes, I think it's bad. I've been using Python since 1.2,
and no other change has had the same consequences
(wrt. time/money required to fix it)
call me a crappy programmer if you want, but I'm sure
there are others out there who are nearly as bad. and
lots of them won't be aware of this change until some-
one upgrades the python interpreter on their server.
