[GHC] #8149: GHC should warn about redundant import of a type name also if one of its record selectors is imported
#8149: GHC should warn about redundant import of a type name also if one of its record selectors is imported ------------------------------------+------------------------------------- Reporter: Lemming | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Keywords: | Operating System: Unknown/Multiple Architecture: Unknown/Multiple | Type of failure: None/Unknown Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | ------------------------------------+------------------------------------- Sorry, I have another corner case for a redundant import warning: {{{ module Main where import Control.Monad.Trans.Writer (WriterT, runWriterT) main :: IO () main = undefined runWriterT }}} This module will not provoke a warning, although the import of WriterT can be omitted. I assume this is because runWriterT is a record selector of WriterT and could (or should?) be imported as: {{{ import Control.Monad.Trans.Writer (WriterT(runWriterT)) }}} Since I used runWriterT like a regular function I did not care about its record selector feature. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8149 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
