And again, YMMV. In my experience, most "while True" loops would be
better off written as a "repeat... until True" loop. But since Python
doesn't have syntax for such repeat until loops, our work-around is to
use a while True and break out of it at the end of the loop.
To be honest, I'm having trouble thinking of a good use-case for "while
True", now that we have infinite iterators. Most cases of
while True:
x = get_item()
if not x: break
process(x)
are better written as:
for x in iterator:
process(x)
