#6018: Injective type families ----------------------------------------+----------------------------------- Reporter: lunaris | Owner: simonpj Type: feature request | Status: new Priority: normal | Milestone: 7.8.1 Component: Compiler | Version: 7.4.1 Keywords: TypeFamilies, Injective | Os: Unknown/Multiple Architecture: Unknown/Multiple | Failure: None/Unknown Difficulty: Unknown | Testcase: Blockedby: | Blocking: Related: #4259 | ----------------------------------------+----------------------------------- Comment(by morabbin): Noting for completeness: possibly related to #7205 and #5591. Why I'm interested: I'm modeling the Java type system in Haskell (overload resolution in particular) a la chak and Andrew's Salsa, using type families and type functions heavily. Their code worked under earlier versions of GHC, but not under 7.4 and beyond. -- Ticket URL: http://hackage.haskell.org/trac/ghc/ticket/6018#comment:15 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
