#10039: Make Const (Control.Applicative) kind polymorphic in its second argument -------------------------------------+------------------------------------- Reporter: Iceland_jack | Owner: ekmett Type: feature request | Status: new Priority: normal | Milestone: Component: Core Libraries | Version: 7.8.4 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by ekmett): Most of the Data.Functor.* suite is amenable to this treatment, yes. I've been programming with rather excessively generalized kinds on a large chunk of code for a couple of years now with surprisingly few problems. However, as we don't currently have those instances in `base` this is definitely a concern for future `base` efforts, not so much for now. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10039#comment:10 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
