Can one get "for x in y" to work for non builtin classes?

Be careful on your descision to return an ordered iterator or not--
that is, whether it iterates over the dictionary or the list (if I
understand you correctly).  If the order's unimportant then please
disregard.

You can also use:

>>> a= [2,3,4]
>>> b= iter( a )
>>> next( b )
2
>>> next( b )
3
>>> next( b )
4
