[Python-Dev] LOAD_NAME & classes

[Greg Ewing]

Guido:

>    def f():
>        print x # user thinks this should print the global
>	# 2000 lines of unrelated code
>	for x in "some sequence": # doesn't realize this overrides x
>           do_something_with(x)

Perhaps a warning could be issued if the first reference
to a local textually precedes the first assignment to it?
Would that help catch things like this, without complaining
about too much existing code?
