Excellent! Guido uses
while [x for x in [bluh()]][0]:
whatever(x)
because he thinks it's "more elegant" (whatever that means to a Dutch guy),
but either way it's major relief from the obscurity of embedded assignment.

Thanks for the suggestion! Some Americans consider it rude to shoot
coworkers, so I'm always looking for ways to get across to them that it's
more a matter of defending good taste than of killing people. Using a piece
with sleek Italian design should go a long way toward helping to make this
point.
