[GHC] #10816: Fixity declaration for associated type rejected
#10816: Fixity declaration for associated type rejected -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.10.2 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Revisions: | -------------------------------------+------------------------------------- When I say {{{ {-# LANGUAGE TypeOperators, TypeFamilies #-} module Bug where class C a where type a # b infix 4 # }}} I get {{{ Bug.hs:7:11: ‘#’ is not a (visible) method of class ‘C’ }}} But it really should just assign a fixity to the type `#`. It works if the fixity declaration is outside of the class. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10816 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler

While Phab:D4077 doesn't implement the proposal in full, it will make it easier to do so later. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10816#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
