Roland, a great open-source developer joined CR with his expertise and I'm excited waiting for the new features will appear in future of CR. He also exposed some bugs in implementation and I was happy to fix them!
- a simple implementation of auto boxing/unboxing is done
- optimizations are defined by category (no command line flag yet) but right now is possible to add just "propagation" optimizations, or just "constants folding" ones and so on
- some old optimizations were not using use-def optimizations, and right now they do. This means in short: they are a bit faster than in the past.
