permuting several lists (was Re: [Python-Dev] zip() and list-comprehension with commas)

[Ka-Ping Yee]

tuples(), lists(), dict(), and indices() look pretty generally useful
to me.  I agree that they look like good candidates for builtins.

This one in particular looks really fabulous.  +1 to put this in builtins.

In order of usefulness (just imho of course):

     irange     +1
     tuples     +0.5
     indices    +0.5
     dict       +0
     lists      +0
