    In Python 2, the queue attribute was a list and it is still documented that way in Python 3: http://docs.python.org/3/library/sched.html#sched.scheduler.queue

    This appears to be a mistake made during the 2-to-3 conversion.

    Perhaps it will be better document it as an iterator? In any case we can call list() to get a list.

    It's pretty weird to use a property for an iterator. It we really wanted iteration, the appropriate method would be __iter__.
