FWIW, there are a few historic languages that implement a compound
for-loop: Algol 68, PL/I, SAS et al allow constructs that, if
translated to an equivalent (currently invalid) Python-style syntax
would look like this"
for in while :
Some also allow for an "until" keyword. I'm not suggest
I wonder if this is a bug?

Right, but the PEP is only about generator expressions.

instead like the first time around, StopIteration will be raised and
(presumably) the generator will terminate.

-intuitive. I would have expected the
parameters in the reverse order (take something, while something else
is true). Tripped me up a few times, which got me thinking about an
alternative.

. So, actually the takewhile version is
two characters longer, not counting "import itertools" of course!

ile(lamda p:p<1000, sieve())
