#7964: GADTs in Haskell98 style -----------------------------+---------------------------------------------- Reporter: wvv | Owner: wvv Type: feature request | Status: new Priority: normal | Component: Compiler (Type checker) Version: 7.6.3 | Keywords: Os: Unknown/Multiple | Architecture: Unknown/Multiple Failure: Other | Blockedby: Blocking: | Related: -----------------------------+---------------------------------------------- Comment(by goldfire): I'm a little confused here. What, exactly, isn't documented? thoughtpolice has just combined the `(~)` syntax with the old syntax... I don't see any undocumented features here. Also, I should note that, even though the definition of `Foo` above compiles without `-XGADTs`, you won't be able to pattern-match on it without enabling the extension. To my mind, it's a small infelicity that GHC accepts `Foo` without `-XGADTs`, but probably not worth doing much about. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/7964#comment:3 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
