#9858: Typeable instances should be kind-aware -------------------------------------+------------------------------------- Reporter: dreixel | Owner: Type: bug | Status: new Priority: highest | Milestone: 7.10.1 Component: Compiler | Version: 7.9 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Type of failure: None/Unknown | Unknown/Multiple Blocked By: | Test Case: Related Tickets: | Blocking: | Differential Revisions: -------------------------------------+------------------------------------- Comment (by simonpj): It's certainly possible to make it possible ''not'' to have `Typeable`. But it's a significant chunk of extra work, and at the moment we pretty strongly believe we'll want to throw it away anyway. I don't think we have a single example of a situation which having `Typeable` is bad. However, if (against all the evidence) someone eventually produces a situation in which we don't want `Typeable` for some type, we can I suppose implement `NoAutoDeriveTypable`. So I don't think we are painting ourselves into any corners. Reasonable questions, but I think we should proceed as planned.
