#11011: Add type-indexed type representations (`TypeRep a`) -------------------------------------+------------------------------------- Reporter: bjmprice | Owner: Type: feature request | Status: patch Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2010 Wiki Page: | -------------------------------------+------------------------------------- Comment (by bgamari): The Core Lint violation in `T11120` appears to be the result of `(->)` overly constrained kind when used in prefix position, `* -> * -> *`, {{{ Kind application error in type ‘(->) Char#’ Function kind = * -> * -> * Arg kinds = [(Char#, TYPE 'WordRep)] }}} Where this type appears in a use of `mkTrApp`, {{{#!hs mkTrApp @* @* @((->) Char#) @CharHash ... }}} which was produced as evidence for the `Typeable` representation for, {{{#!hs data CharHash = CharHash Char# }}} I've opened #11714 to track the overly constrained kind of `(->)`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11011#comment:40 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
