EPython is a typed-subset of the Python language useful for extending the language with new builtin types and methods.
The goal is to be able to write things like NumPy, SciPy, Pandas, bitarray, and any other extension module of Python in this language and get equivalent or better perfomance than writing it using the C-API typically provided.
This project is in development and extremely alpha. You should not use this.
