[Python-Dev] list.shift()

Has list.shift() been proposed?

    # pretend lists are implemented in Python and 'self' is a list
    def shift(self):
        item = self[0]
        del self[:1]
        return item

This would make queues read nicely... use "append" and "pop" for
a stack, "append" and "shift" for a queue.

(This is while on the thought-train of "making built-in types do
more, rather than introducing more special types", as you'll see
in my next message.)
