A strong +1 here also.

As I understand current plans, Python 3 will have a polymorphic integer type
that handles details of switching between the two current implementations,
one for efficiency, and one for generality, behind the scenes.
I think it would be a great selling point for people to adopt Python 3 if it
also handled the even worse nastiness of text forms behind the scenes, and
kept the efficiency of special case uses (as in all ascii chars) while
making the transition to generality more seamless than it is now.
These two similar features would be enough, to me, to make Py3 more than
just 2.x with cruft removed.
