Remember the "string join" debate?

There is no sequence base class in Python (it's an informal inter-
face, not a type), so where would you put that method?

As specified, "zip" has a *single* implementation which takes
any number of objects implementing the sequence interface,
and return an object implementing the same interface.  Can it
be much simpler?

-1 on a method.  Python is moving towards more genericness
(if you accept an integer/sequence/string, you should be able
to deal with any kind of integer/sequence/string).  Adding a
method would be a move in the opposite direction.
