I'm glad to hear it :) I really think this project is awesome and has huge potential.
I really wanted to submit bug fixes, I tried looking at jhc source but I wasn't sure where
to look at except for C.FromGrin, C.Generate but I still wasn't sure where to begin.
I have very little knowledge and no experience with PLT & compiler technology.

significant amount of time to finish before moving on.
