#4426: Simplify the rules for implicit quantification -------------------------------------+------------------------------------ Reporter: simonpj | Owner: Type: feature request | Status: new Priority: low | Milestone: 7.6.2 Component: Compiler | Version: 6.12.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: #7880 -------------------------------------+------------------------------------ Changes (by monoidal): * difficulty: => Unknown * related: => #7880 Comment: See also comments at #7880. This change is not hard (I had a very rough sketch that detected ~4 missing quantifier errors in GHC tree) but it's too late for 7.8. Maybe I'll do it such that 7.10 will give a warning and 7.12 an error. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/4426#comment:6 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
