#15687: Type synonym unused binds no warning? -------------------------------------+------------------------------------- Reporter: AntC | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: 8.6.1 Component: Compiler | Version: 8.6.1 (Parser) | Resolution: | Keywords: Operating System: Windows | Architecture: Type of failure: GHC accepts | Unknown/Multiple invalid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): You could argue that you should get a warning about "unused `a`" in `Silly`'s definition. But we don't warn about {{{ const x y = x }}} so you might consider it inconsistent to warn about the same thing at the type level. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15687#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
