Hey John,
The language you are working on - is it a EDSL in Haskell? If not, had you considered such an option?

Yeah Atom is pretty slick, though unfortunately it's not quite powerful enough for much of the stuff that we do.

John Van Enk and I are actually working on a language that's similar to C (and compiles to C), but has polymorphism, type inference and other goodies. The goal is to make working on embedded systems a bit less painful, while still being able to do anything that C can do (like run on an 8 bit micro).
Hopfully, if things go as planned, we'll have a working beta out by the end of the month :)

Or look at EDSLs, like Atom:
