#5462: Deriving clause for arbitrary classes -------------------------------------+------------------------------------- Reporter: simonpj | Owner: dreixel Type: feature | Status: new request | Milestone: ⊥ Priority: normal | Version: 7.2.1 Component: Compiler | Keywords: Generics Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: #7346 None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by simonpj): You know what I'm going to say. Can you write a wiki page that specifies the feature, as seen by the programmer, as precisely as possible. When it is legal? What instance declaration is generated? What is the context on that instance declaration. If there are any implementation wrinkles, they can appear in a separate section on the wiki page.
