(This reminds that I wish ``iter`` could take a predicate instead of a sentinel as its second argument. Then
you could just write

for cmd in iter(get_command, lambda x: x.token == CMD_QUIT):
cmd.do_something()
)

But you can do it right now:

class P:
    def __init__(self, key):
        self.key = key
    def __eq__(self, other):
        return self.key(other)

for cmd in iter(get_command, P(lambda x: x.token == CMD_QUIT)):
    cmd.do_something()

With kind regards,
