And you'll really want those tests if/when you do optimize for speed.

Rather it is the time you spend working on the

Exactly -- or even if you aren't an academic, development time is far more
valuable than run time.

They key here is that Cython is really great, and can be very easy to use
-- but it is not at all cost free. The edit-compile-test cycle is much
slower, and it's a lot harder to debug than Python -- so you really don't
want to use it unless there is a real gain to to doing so.
