Hmm I think this also applies to list_listiterator. In general I'd expect these

def gen():
l = [itertools.permutations(range(10)) for _ in range(10)]
g = itertools.product(*l)
for i in g:
yield i
A simple next() to this generator takes 16 seconds on my

if every characters in this `str` is in ASCII range, or a `bytes`.
This is confusing for new comer because:

For the `plistlib` package, from Apple's own manual[1], there's actually a
third JSON format.
It'll be good to indicate that `plistlib` doesn'
