#9043: Add missing type class instances for data types in GHC.Generics -------------------------------------+------------------------------------- Reporter: ocharles | Owner: dreixel Type: feature request | Status: new Priority: normal | Milestone: 8.0.1 Component: Core Libraries | Version: 7.8.2 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: 9766 | Blocking: Related Tickets: #8778 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): I checked, and it turns out that derived `Traversable` instances for `URec` won't kind-check at the moment. This isn't a fundamental limitation of `Traversable`, however. I've opened #11174 regarding this issue. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9043#comment:35 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
