I agree in principle, but I thought the proposed syntax already has
meaning today (as it turns out, parentheses are required to make a
tuple in a while condition, at least in 2.4 and 2.5). To help stave
off similar confusion I'd rather see a pseudo-keyword added. However
my first candidate "until" seems to apply a negation to the exit
condition.
while True until False: # run once? run forever?
while True until True: # run forever? run once?
It's still very different from any syntactical syntax I can think of
in python. I'm not sure I like the idea.
