I hope some day some big corp decides to write a decent (open source) Python to C compiler, which makes optional optimizations based on type annotations.

I find this project: https://github.com/Nuitka/Nuitka very interesting, but its written and maintained only by a single person and I never got it to work with any of my apps.

Cython is a pretty good Python to C compiler and in its latest release is using type annotations... the thing is, you shouldn't need to compile your whole program (compiling is really slow and interpreted Python is fast enough for most of the code).

I was under the impression that Cython is a different language (a subset / dialect of Python). So, not a Python to C compiler.
