#6018: Injective type families -------------------------------+------------------------------------------- Reporter: lunaris | Owner: simonpj Type: feature | Status: new request | Milestone: 7.10.1 Priority: normal | Version: 7.4.1 Component: Compiler | Keywords: TypeFamilies, Injective Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: #4259 None/Unknown | Test Case: | Blocking: | -------------------------------+------------------------------------------- Comment (by hpacheco): To get going, I wouldn't mind if the onus of proving that the type family is indeed injective fell on me, in an unsafe way. But I understand that it is clearly not a feature that you should blindly introduce in mainstream GHC... I may look into it in the future if I ever find the time, but I doubt it. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/6018#comment:30 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
