#13044: make it possible to apply GHC rewrite rules to class methods -------------------------------------+------------------------------------- Reporter: George | Owner: Type: task | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Keywords: | Operating System: Unknown/Multiple Architecture: | Type of failure: None/Unknown Unknown/Multiple | Test Case: | Blocked By: Blocking: | Related Tickets: Differential Rev(s): | Wiki Page: -------------------------------------+------------------------------------- Make it possible to apply GHC rewrite rules to class methods. As Conal wrote in a discussion on glasgow-haskell-users, it is too bad that we can't use class laws as optimizations in the form of rewrite rules. In that same thread Simon PJ referenced https://ghc.haskell.org/trac/ghc/ticket/11688, esp comment:7 which gives links to similar examples. https://ghc.haskell.org/trac/ghc/ticket/10528 comment:13 gives more background. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13044 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
