Thanks for the analysis, but I'm afraid I must disagree with your
recommendation. It was the thought I first had when Chris came out with
his first draft of the PEP several months ago, but it's not enough to
cope with my usual use cases. What I normally want is the Python
equivalent of:
while ((v = get_something()) != INCONVENIENT_SENTINEL)
do_something(v);
The condition expression itself is not what I want to capture; I need a
subexpression, which the "as" syntax won't give me.
