#11370: Redundant superclass warnings being included in -Wall destroys the "3 Release Policy" -------------------------------------+------------------------------------- Reporter: ekmett | Owner: bgamari Type: bug | Status: new Priority: highest | Milestone: 8.0.1 Component: Compiler (Type | Version: 7.10.3 checker) | Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #11369, #11429 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): One open question here is how this should interact with #10632, which requests warnings for unused implicit parameters. This was addressed with `-Wredundant-constraints`, which we are now disabling by default. Is it reasonable to expect users to enable `-Wredundant-constraints` to be warned of unused implicit parameters? Implicit parameters "feel" a lot more like arguments than constraints. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11370#comment:19 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
