Have you look at mypyc? https://github.com/python/mypy Its a compiler that support subset of python and mypy's team including Guido work on it. It would be great if this kind of efforts have been done on more realistic project.

I was surprised to find out that MyPy will throw an error if you use a variable to access a key ( https://github.com/python/mypy/issues/7178 ). Optional keys are also a nuisance.
