First, a few points
- the community isn't rewriting the compiler, they are rewriting the language
- the design of the language has never been secret
- it's hard to open-source something that has no source yet
Do you begrudge Patrick and Luke some private time to get their act together? You'd rather that happen in public? Do you fear that they will head off in the wrong direction or that they will miss something vitally important before publicly releasing code?
Or are you afraid they'll waste time covering ground that's already been covered (as I glean from another post in this thread)? I see this as Patrick's time to ramp-up. Even if he covers already-covered ground that's okay because he's the one charged with doing the work and he needs to learn the things he needs to learn to get the job done.
