#13774: Singletons code fails to typecheck when type signature involving type family is added -------------------------------------+------------------------------------- Reporter: RyanGlScott | Owner: (none) Type: bug | Status: closed Priority: normal | Milestone: Component: Compiler (Type | Version: 8.0.1 checker) | Keywords: FunDeps, Resolution: invalid | TypeFamilies Operating System: Unknown/Multiple | Architecture: Type of failure: GHC rejects | Unknown/Multiple valid program | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by RyanGlScott): Urgh. I'd like to feign ignorance and claim that I would have never thought in a million years to put in a kind ascription, but this isn't even the first time that this bug has bit me (#11275). So I should probably know better by now... but thanks for patiently explaining to me again anyways :) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13774#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
