Given the number of extensions used in ghc's own code, many of which jhc does not support, this seems unlikely, at least not without first mechanically converting its code to an intermediate form like Haskell 98. Also, jhc would still need to be ported to new arches. ;) Also, you'd probably need quite a lot of memory (probably gigabytes) to compile something as large as ghc with jhc, since jhc is lacking even garbage collection. It'd be nice to have jhc in Debian though. Although the Haskell compiler we really need, IMHO, is Fay. -- see shy jo signature.asc Description: Digital signature

How actively is it maintained (last commit is 9 month ago)? Haskell-World is full of experiments that are great, but not really much used when packaged into a Debian package.

I agree that Fay is a great tool, but I’m not sure it is ready yet, not even supporting let (x,y) = ..., let alone type classes. Too bad that they are not based on GHC core, that would make a lot of things easier. Also, the problem of how to distribute libraries for Fay is not solved yet. But of course: Please do remind me from time to time to reconsider, as Fay (or one of its competitors) evolves.
