Thanks, but this won't register itself as a package with current ghc,
and even I fixed that problem I guess it probably still wouldn't
work :-(

It's entirely up to you folks of course. I don't know if anyone at GHHQ
cares enought to do anything about the buildability problem. But if not
I'm afraid I can't see this being used or accepted as part of standard
Haskell infrastructure. It'll just be something people look at, admire
the coolness, maybe even tinker with for a while, but never really use
for anything serious.

Meanwhile I think the GSoC project I mentioned will have to make other
arrangements :-)

To be honest though, I'm not sure we'd use it anyway as I understand
it generates essentially pure H98 and there are ghc extensions we'd
probably want to use for performance reasons (like unboxed Ints and
unboxed tuples).
