#10988: Suggest LambdaCase -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: high | Milestone: 8.0.1 Component: Compiler | Version: 7.10.2 (Parser) | Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- When I say {{{#!hs module Bug where foo = \case True -> False False -> True }}} I get {{{ Bug.hs:9:7: error: parse error: naked lambda expression '' }}} We can do far better. Setting priority to high because it's rather embarrassing to let your lambdas run around naked. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10988 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

Although I forgot to say so on the ticket, I tested against HEAD. But it's a slightly old HEAD. I guess this is fixed.
