I think this is a blocker, but it seems it is on its way to be fixed:

"Pythran supports Python *2.7* and also has a beta Python *3* support."

scipy has a lot of Cython code, much of it fairly well tested, which can be
very useful for testing Pythran itself.

A question, does Pythran eliminate the need for storing intermediate
results? Like (a*a).sum(axis=1) for a large a, will it store the full
a-squared? (If it is, I'd be very sorry I didn't run into it earlier, and
very happy I finally did).
