did you see this, and the discussion around that time? http://www.haskell.org/pipermail/haskell-prime/2012-May/003688.html
I implemented hDeleteMany without FunDeps -- and it works in Hugs (using TypeCast -- but looks prettier in GHC with equality constraints).
I'm afraid I didn't see that -- I was on travel during that time. It is nice that hDeleteMany works on Hugs. I forgot if we tried it back in 2004. To be sure some HList code did work on Hugs. We even had a special subset of HList specifically for Hugs (which I removed from the distribution some time ago). The problem was that Hugs inexplicably would fail in some other HList code. Perhaps 2006 version is better in that respect, and more or all of HList would work on it. Thank you.
