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).

I also like the above, but as a more general assignment-in-expression, not as a statement-local -- the difference being that there would be no auto-deletion of the variable, no confusion about when it goes away, no visual name collisions (aside from we have already), etc., etc.

Maybe I'll write yet-another-competing-PEP.  ;)
