There's also the case where people blindly put something like "base < 10" in the .cabal file, and then it broke on the next GHC release. This happend with ghc-core-0.5: it completely failed to build with base-4 (and because cabal-install kept defaulting packages to use base-3 I think a lot of people missed cases like this and blindly thought it worked). I like having upper bounds on version numbers... right up until people abuse them. -- Ivan Lazar Miljenovic ivan.miljeno...@gmail.com http://IvanMiljenovic.wordpress.com _______________________________________________ Haskell-Cafe mailing list Haskell-Cafe@haskell.org http://www.haskell.org/mailman/listinfo/haskell-cafe
