#9429: Alternative to type family Any -------------------------------------+------------------------------------- Reporter: mboes | Owner: Type: feature | Status: new request | Milestone: Priority: normal | Version: 7.9 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: 9097, 9380 None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): I'm sorry, but I still don't understand the problem. Why exactly do you need a `Typeable` instance for types involving `Any`? In the example you give in "Context", you could perfectly well declare your own data type `MyAny` and use it instead of `Any`. Can you give a more complete example that shows why it's essential to have a `Typeable` instance for GHC's `Any`?
