Pyjion – A Python JIT Compiler

HN discussion on the repo from which this is forked: "Pyjion – A JIT for Python based upon CoreCLR" https://news.ycombinator.com/item?id=10984514 (Jan 28, 2016 | 23 comments)

This is the first time I've learned of this. How it compares to PyPy [1]:

> PyPy is an implementation of Python with its own JIT. The biggest difference compared to Pyjion is that PyPy doesn't support all C extension modules without modification unless they use CFFI or work with the select subset of CPython's C API that PyPy does support. Pyjion also aims to support many JIT compilers while PyPy only supports their custom JIT compiler.

Apparently it's originally a Microsoft project, and it requires .NET. The project already exists for a few years, but it looks like they've gained net performance improvements over CPython only the past few months [2].

No, it's cpython in a trenchcoat, not written in .net, not ridding the .net vm. But it uses the JIT from .net.

Is this a modern version of Psyco?

Can the dotnet dependencies be installed in Python?
