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 dosomethingwith(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?
