[New-bugs-announce] [issue3891] collections.deque should have empty() method

[Roy Smith]

New submission from Roy Smith <roy at panix.com>:

Unless I'm missing something, the only way to tell if a deque is empty is 
to try and pop() something and catch the resulting IndexError.  This is 
not only awkward, but mutates the data structure when you may not want to.

It should be trivial to implement, and run in O(1) time.
