#12594: DeriveAnyClass fails to derive some classes -------------------------------------+------------------------------------- Reporter: ivanm | Owner: Type: bug | Status: new Priority: normal | Milestone: Component: Compiler | Version: 8.0.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by simonpj): Yes, documenting this better would be a Jollly Good Thing. Also pointing out that if the (necessarily fallible) heuristic for deducing a context fails, you can always us a "standalone deriving" declaration to specify the context yourself; it's a bit like adding a type signature. Ryan or someone -- would you like to suggest a documentation patch?
