Hello all, Thanks for the great feedback so far on the split package. I have updated the wiki page with the results of the discussion so far: http://trac.haskell.org/haskell-platform/wiki/Proposals/split In particular, I have made the following changes to the package as a result of the feedback: * Removed the GADTs extension; the package is now fully Haskell 2010. * Marked synonyms as deprecated, and excluded them from the Haddock output. Thus new users will not be confused by the synonyms anymore, and existing users will be notified that they are now deprecated, but existing code will not break since the synonyms are still exported from the package. * Many other minor cleanups and improvements to documentation etc. More details are on the wiki page. These changes are in the darcs repository but I have not released a new version to Hackage yet. * I am also looking into the possibility of using conditionals in the .cabal file to support both GHC and other compilers, by using GHC's primitive 'build' function only when GHC is the compiler, and otherwise using a generic one. More feedback on this is appreciated. Is it worth the effort/complication? Please continue responding to this thread (or the previous one) with additional feedback, upvotes, downvotes, etc. -Brent
