I'd much rather see a patch that just changed zip() to be an iterator
instead of adding an iterzip(). I doubt that much in-field code would
break because of it (but write the PEP to find out. ;).

The PEP would have to specify a migration plan, i.e. the builtins are
identical to the functional module versions, and would a deprecation
schedule, etc.
