#9200: Milner-Mycroft failure at the kind level ----------------------------------------------+---------------------------- Reporter: ekmett | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler (Type checker) | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects valid program | Unknown/Multiple Test Case: | Difficulty: Unknown Blocking: | Blocked By: | Related Tickets: ----------------------------------------------+---------------------------- Comment (by dolio): Having conferred with Ed, I guess GHC uses a different strategy that doesn't involve (proper) skolem variables, so it might not be subject to my complaint. Using some kind of after-the-fact distinctness check instead of proper skolems seems not to arbitrarily rule out certain definitions in a confusing manner, which was my main concern. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9200#comment:13 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
