Thanks. As bot is morally green, I am setting to positive.

Jeroen, do you agree on the idea of adding "absolute_import" to all pyx files ?

Jeroen, do you agree on the idea of adding "absolute_import" to all pyx files ?

1. If you want to do that, why not all files (both .pyx and .py)?

2. If you want to do that, why not add division, print_function everywhere too?
