#14273: Typed holes' "valid substitutions" suggestions are oblivious to type class constraints -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: Tritlo Type: bug | Status: new Priority: normal | Milestone: 8.4.1 Component: Compiler (Type | Version: 8.3 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Poor/confusing | Unknown/Multiple error message | Test Case: Blocked By: | Blocking: Related Tickets: #9091, #9479 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Tritlo): Replying to [comment:11 simonpj]: Thanks for the clarifications. I'll aim for making it work for the common cases then. Replying to [comment:12 vanto]: Well, they're (kind of) not on by default, you have to have a typed hole in your code for it to trigger. What other behaviour do you want when `_` is encountered in expressions? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/14273#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
