#8263: allow duplicate deriving / standalone deriving -------------------------------------+------------------------------------ Reporter: aavogt | Owner: Type: feature request | Status: new Priority: normal | Milestone: Component: Compiler | Version: 7.6.3 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: Unknown/Multiple Type of failure: None/Unknown | Difficulty: Unknown Test Case: | Blocked By: Blocking: | Related Tickets: -------------------------------------+------------------------------------ Comment (by simonpj): I'd rather not. It's another rule to implement and document in the manual. Why not put `deriving Typeable` on the declaration of `Flag`?
