Hello GHC HQ, I wanted to inform you that I created the `ghci-ng` package http://hackage.haskell.org/package/ghci-ng-7.6.3.3 which essentially is the ghc/* folder from the GHC source-tree with a ghci-ng.cabal file put in place (and some dummy .h files) to make the interactive-mode GHC front-end compilable w/o requiring the full GHC source-tree. The reason I created ghci-ng was to be able to backport features from GHC HEAD so that Haskell user not living on the bleeding edge (such as Haskell Platform users) don't have to wait for half a year or so till they can use new features[1]. On the other hand, this might also allow to expose new work-in-progress features to users in production environments to play with before those features find their way into a final GHC release, and thus help with developing new GHCi features in a more "agile" way by getting feedback from potential users earlier. So ghci-ng is *not* supposed to replace ghci, but rather provide an testing ground for evaluating new/experimental features which may get merged into upstream GHCi eventually if they prove useful. Please let me know what you think of this. [1]: The killer-feature right now being the new `:complete` command which allows the latest (unreleased) haskell-mode to provide REPL-completion from within the Emacs buffer. Cheers, hvr
