The lack of compilation time in Python is a false economy when you consider the cost of tacking on the type checker and the developer time spent wondering whether the type that's been annotated is accurate. Static typing is good for developer velocity.

Not to mention that cythonization might be part of the pipeline and can have bugs that only show up post-cythonization.

I really dislike python in production and have done it a lot more than I've ever wanted.
