#9117: Coercible constraint solver misses one -------------------------------------+------------------------------------- Reporter: goldfire | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.8.2 Resolution: | Keywords: Operating System: | Architecture: Unknown/Multiple Unknown/Multiple | Difficulty: Unknown Type of failure: | Blocked By: None/Unknown | Related Tickets: Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Changes (by nomeata): * owner: nomeata => Comment: This ticket started with `eta :: Coercible f g => Coercion (f a) (g a)` and then discussed the order of our existing solving steps (which was then changed). But nothing happened about `eta :: Coercible f g => Coercion (f a) (g a)`. Is there a real use case for this? Do we have an idea how to integrate that? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/9117#comment:31 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
