I've yet to see anybody arguing for while loops to be nested like
that, but we already allow nested for loops in comprehensions and
generator expressions:

[(x, y) for x in a for y in b if c(y)]

Why not allow the same thing in for-loop conditions?  I think that
anything that makes the language syntax more consistent is good.

Cheers,
