I have just checked on Windows, it works the same way. Thus I have the gut feeling that something in GHC itself was changed, this is not related to the actual platform. Perhaps the consequent `-e` flags are not processed any more, only the first one? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9905#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

See #7962. That could explain all the results here, except that in ghc 7.6, `-e "import Data.List"` actually works: try `ghc-7.6.3 -e "import Data.List" -e "sort [2,1]"`. This no longer works in ghc 7.8, so there is certainly something to fix here. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9905#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
