I think Herbert was leaning towards `-Weverything`.
Possibly with Gershom's suggestion from the mailing list of making unrecognized `-Wfoo` options emit a single warning about an unrecognized
Indeed, because we have a precedent in `clang` which uses `-Weverything` for that very purpose (since `-Wall` is traditionally doesn't comprise *all* warnings for gcc/clang, which is probably also the origin from where GHC copied this tradition...) Replying to [comment:8 ekmett]: option rather than have the compiler emit an error and die. Filed as #11429 -- if we agree this is a sensible thing to do, I think we should try to get this done in time for GHC 8.0 to extend the compat- window as far back as possible, i.e. starting at GHC 8.0 for a `-Wno- unrecognised-warning-flags` (module bikeshed) support -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11370#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
