#13064: Incorrect redudant imports warning -------------------------------------+------------------------------------- Reporter: phadej | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple error/warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Helpful example, thank you. Just for context, in comment:12, I guess `Control.Applicative` exports `pure` and `<$`. * So the use of `<$` needs `import Control.Applicative` * The use of `pure` could come from `import Prelude( IO, pure )` or from `import Control.Applicative`; but for some reason GHC 8 chooses the former, whereas the rules in wiki:Commentary/Compiler/UnusedImports says the latter. Is that your reasoning? Are you saying "I like the rules in wiki:Commentary/Compiler/UnusedImports, but they aren't being implemented", or are you saying "I'd like different rules"? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13064#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
