The proposed syntax would suggest that this should be legal as well:
for i in iterable while cond:
blahblah
or perhaps:
while cond for i in iterable:
blahblah
A while-for or for-while loop would be a novel invention, not seen in
any other language that I know of. I seriously doubt its usefulness
though...
