My assessment is exactly the same as yours.
I call the app 2 times: one for code, another for doctests.
The setup.py that I provided only does code precisely because of this.
I still did not have time to, programatically, call both
transformations.
So: yes it sucks.

Talking about setup.py, its current incarnation is broken on Python 3.
Even if the objective is for it to print some information on calling
2to3 it will not work. Just putting the prints with () should sort it
(and work everywhere)
Anyway, I think we can make setup.py much more helpful in the p3 case
by calling 2to3 (like numpy). The tests would also need to be
transformed, I think.
