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. -- Rhodri James *-* Kynesim Ltd
