#11451: Inconsistent warnings for unused binders in type and instance declarations -------------------------------------+------------------------------------- Reporter: simonpj | Owner: Type: bug | Status: patch Priority: normal | Milestone: 8.0.1 Component: Compiler | Version: 7.10.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: Incorrect | Unknown/Multiple warning at compile-time | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1825 Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): I wholeheartedly agree with your points, although if we introduce a `-Wunused-foralls` flag, it will probably be confusing to also have `-Wunused-type-variables`, since `forall`-ed variables ''are'' type variables, after all. I think it might be better to rename `-Wunused-type- variables` to `-Wunused-type-patterns` in light of this (especially since you want to emphasize the distinction from `-Wunused-foralls`). -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11451#comment:32 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
