So far, implements just append() and popleft() methods, required for a normal queue. Constructor doesn't accept an arbitarry sequence to initialize from (am empty deque is always created), so an empty tuple must be passed as such. Only fixed-size deques are supported, so 2nd argument (size) is required. There's also an extension to CPython - if True is passed as 3rd argument, append(), instead of silently overwriting the oldest item on queue overflow, will throw IndexError. This behavior is desired in many cases, where queues should store information reliably, instead of silently losing some items.
