[Python-ideas] "While" suggestion

Python explicitly disallows inline assignment ("while
a=myfile.read():") because of the error propensity when confusing it
with the comparation ("=="). But here we're gaining the same
advantage, without that risk.

So, taking into account that...

a) We already have "as" as an statement.

b) We already use "as" as an assignment [1]

c) This will allow more concise and intuitive code

... I'm definitely +1 to this proposition.

In any case, Stavros, this would need a PEP...

Thank you!
