Yeah, I discovered that bug too. Not sure what exactly introduced it but i was messing with the renamer. I temporarily disblede utility-ht until I get a chance to look at it again.

I am innocent.

Well, it isn't really base 1.0, it has no relation to the hackage/ghc version other than the unfortunate shared name and the fact they implement similar things which can be confusing. There is no correspondence between the version numbers but it does support many of the interfaces that newer versions of ghcs base has, so you can generally compile cabal projects by simply deleting their build-depends and letting jhc loose on it.

For me a package that tracks the various simple additions to Data.List and Control.Monad, while omitting more complicated stuff like concurrency, would be nice. I would really like to write packages that can be compiled on both GHC and JHC without cabal switches.
