Agreed. Actually I will add this:

enqueue(a::Vector, item) = unshift(a, item)

because if somebody implemented a separate `Queue` type they would only want to implement `enqueue`. "Shifting" to me seems to be related to array-like containers (the name might be chosen to alert you to a possible O(n) run time).
