#9756: Warn about unnecessary unsafeCoerce -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.9 Component: Compiler | Keywords: (Type checker) | Architecture: Unknown/Multiple Resolution: | Difficulty: Unknown Operating System: | Blocked By: Unknown/Multiple | Related Tickets: Type of failure: | None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by goldfire): I'm intrigued by this idea. But, it would surely have a performance impact, if extra analysis must be done on every use of `unsafeCoerce`. Would this be opt-in? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9756#comment:1 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
