Yay!
I haven't downloaded it yet (I'll get to it in a few days :) ), but it looks pretty much exactly like what I was aiming for, which is very nice to see! There is only one really small and minor thing - we have decided to use the namespace Yhc instead of YHC, since the compiler is "officially" called Yhc. It would be nice if we could put this in the main Yhc, if thats ok by you. I'm not sure if we can give you commit access, but I'll look into it, and otherwise we can figure out a remote darcs repo and then pull from it as required. And also it would be nice for the back end of the compiler to use this as well. The only remaining this is the license, since none of the original nhc code made it to this side of the compiler, the only people with copyright on this stuff (or anything related to it) are you, me and Tom. Me and Tom both think that maybe LGPL would be more appropriate for this library, on the basis that then people can use the library from both a GPL program and a BSD program, and it seems that BSD is the prefered license for Haskell stuff, so it makes us more compatible. Thanks for this great work! Neil
