That last part is exactly what I was thinking of. One way in which cythonizing your code isn't 100% compatible is that if you, say, shadow or replace int or range, the cython code is now wrong. Which is exactly the kind of thing FAT can guard against. Which is very cool. Glad to see you already thought of that before me. :)
