#3085: warn about language extensions that are not used -------------------------------------+------------------------------------- Reporter: | Owner: PVerswyvelen | Status: new Type: feature | Milestone: 7.10.1 request | Version: 6.10.1 Priority: normal | Keywords: warnings Component: Compiler | extensions language Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: #9757 None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by goldfire): Though it seems impossible to draw an obvious boundary between this idea and the one posed in #9757, I tend to think the warning proposed here ''does'' belong within the domain of GHC. I don't have an obvious way to implement this in mind, though, and I'm struggling to explain ''why'' I feel this is something GHC should do. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/3085#comment:35 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
