Exactly my thoughts -- it seemed like a crazy research project, generating an interpreter written in C, and ones for jvm and clr. And it has 3 different pluggable garbage collectors apparently.

But I'm impressed that it actually runs my code, in contrast to the other alternative Python implementations I've tried.

Look forward to seeing more of sandboxed mode, which has been a much desired feature of CPython for many years now. And stackless mode. I just hope they can get the executable size and build times to a reasonable level.
