The CIL dynamic re-compiler has a well-developed optimizer and a bunch of other stuff, including an awesome garbage collector. The newer version use a compacting garbage collector IIRC; though Python might use reference counting internally (it might be better that way, but consider the interpreter itself would be in CIL and use reflection ...). It's basically Python -> CIL -> CIL optimizer, not Python -> CIL -> C# optimizer. Granted, yes, an optimizer aware of specific language ABI specifics (like classes for C++, functions and structures for C, ect) can pre-optimize and then let the lower level optimizer re-optimize the code better (I think that's how GCC does it, optimizes a Gimple tree based on language and then does a general optimization based on hardware); but a CIL reflection compiler could compile Python into an internal tree, optimize it, emit optimized CIL, and let Mono generate optimized x86 code (as in, optimize the generated x86 code). > Disclaimer: I have no experience to back this up.
