[GHC] #8534: DeriveFunctor and PolyKinds
#8534: DeriveFunctor and PolyKinds -------------------------------------+------------------------------------- Reporter: monoidal | Owner: Type: bug | Status: new Priority: low | Milestone: Component: Compiler (Type | Version: 7.6.3 checker) | Operating System: Unknown/Multiple Keywords: | Type of failure: GHC rejects Architecture: Unknown/Multiple | valid program Difficulty: Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | -------------------------------------+------------------------------------- A tiny infelicity: {{{ {-# LANGUAGE DeriveFunctor #-} data A a = A deriving Functor }}} works only if `PolyKinds` is disabled, otherwise it reports that `A` has kind `k -> *` instead of expected `* -> *`. On the other hand, standalone deriving works fine. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8534 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
