#9515: Deprecate -XExplicitForAll -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.8.3 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by dfeuer): This only affects code that does something a bit strange. In particular, it has to use a `forall` in an outer position (not for a higher-rank type or an eqxistential) and it reuse the same type variable without a new `forall`. I'd be happy to participate in a survey of Hackage code, but I'm not sure how to go about that—there are thousands of files on Hackage. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9515#comment:9 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
