This is a drop-in replacement for the CPython bytecode interpreter, right? Didn't Microsoft also recently announce something similar? I could have sworn I saw a thread about it here recently, but i couldn't find it again. Or was that the Facebook project Cinder? There are so many "high performance Python" projects now (and in the past) that it's hard to keep track!
