Cython compiles Python with optional extensions that allow additional

language is a Python superset.
I am assuming here that the claim to have reached this goal is correct.
You're right. What I question is the fact that anybody uses Cython
without the additional syntax. There is little chance that a "pure"

Cython (or, if it does, it means that the "canonical" Python interpreter
has some sub-optimal behavior that will, eventually, be corrected).
I believe that there is some inherent overhead that Cython bypasses.
