this decision to change the default syntax in GHC7
what decision? what syntax? here's the release notes (7 vs. 6) http://www.haskell.org/ghc/docs/7.0.1/html/users_guide/release-7-0-1.html I guess you are referring to hierarchical module names? (import List => import Data.List) Indeed, I cannot build WASH http://hackage.haskell.org/package/WashNGo-2.12.0.1 on ghc-7.6.3, and I don't see how it could have worked on 7.0, as hackage claims it did. (building the executables: when using base and haskell89, "import Prelude" is ambiguous; when using haskell98 only, modules like System.Exit are not available.) I think this could be fixed in a straightforward way, but that "fixing it" is necessary at all, just proves your point. - J.W.
