I like this, and I'd like for it to be in python, although I don't
think it will be widely supported because it only saves one line, and
the idiom it replaces isn't very common. [Which facts didn't prevent
the adoption of '@' decorator syntax, but I digress...]  A question
for the sake of completeness: would the following:

if not foo() as x:
    ... x

mean this:

x = foo()
if not x:
    ... x


cheers,
