Hi everyone, Following the great feedback I got on the initial proposal, and after testing with the GHC 7.6 release candidate, I have just released split-0.2.0.0, which I am proposing for inclusion in the HP. The full proposal, links to previous discussion, etc. can be found on the wiki: http://trac.haskell.org/haskell-platform/wiki/Proposals/split Comments, questions, constructive criticism, etc. are still welcome, but this time around I hope we can build a consensus as to whether it should go in the platform or not. I would also like people's opinions on the one big question remaining: whether to use cabal's mechanisms to conditionally include some code, allowing the 'build' function to be taken from GHC.Exts when available, or defined manually otherwise. This would make split fully H2010-compatible. The currently released version does NOT include this, so it is H2010-compatible but GHC specific. The options are: 1) just use a generic version of 'build' (simplest option) 2) use only GHC's version of build (slightly faster) 3) do the conditional thing to choose between 1) and 2) at compile time (most general but most complicated/cumbersome) -Brent
