[Haskell-cafe] compilation to C, not via-C

I really like the idea of the region based mem management (and other GC
options) in JHC. It could potentially remove the need for any runtime at
all, which is nice.
Two fundamental differences of Timber is that it is purely strict, and not
This makes the implementation and use of IO intensive systems slightly more
Also, when I tested JHC, I couldn't get it to compile my test case. Note
that I am not qualified to speak on the quality of the compiler since my
Haskell skills are mediocre at best.
One big advantage of JHC once it matures is that it will be able to leverage
the cornucopia of haskell libs in hackage, wheras Timber will have to start
pretty much from scratch.
