[Python-ideas] PEP 572: Statement-Local Name Bindings

[Alex Walters]

For what its worth, I'm +1 on it.

I actually like that it would allow:

while (something() as var):
    something_else(var)

...without being a bug magnet.  The bug magnet isn't the assignment of a
name in the condition of a while loop, it's the fact that assignment is a
simple typo away from comparison.  This is not a simple typo away from
comparison (the operands are a different order, too).

(sorry Chris, I didn't hit reply all the first time.)
