I've been programming with Haskell for a few years and love it. One of my favorite applications of Haskell is using for domain specific languages. However, after designing a handful of DSLs, I continue to hit what appears to be a fundamental hurdle -- or at least I have yet to find an adequate solution.

It seems to become a FAQ. I think all DSLs suffer from the same problems: sharing and recursion. I've used wrappers for CSound, SuperCollider, MetaPost, they all have these problems.
