I would disagree... This sure works for empty arguments, but:
>>> u = [1,2,3]
>>> a = Queue(u)
>>> b = Queue(u)
>>> a.insert(12)
>>> print b
gives [1, 2, 3, 12] which is still wrong. However assigning self.queue a COPY
of parameter (empty or not) gives the desired result:
def __init__(self, q = []):
self.queue = q[:]
