#10598: DeriveAnyClass and GND don't work well together -------------------------------------+------------------------------------- Reporter: osa1 | Owner: RyanGlScott Type: bug | Status: patch Priority: normal | Milestone: 8.2.1 Component: Compiler | Version: 7.11 Resolution: | Keywords: Generics Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D2280 Wiki Page: | -------------------------------------+------------------------------------- Comment (by nomeata): Motivated by the lightning talk, a note on the wording “bespoke”. To me, “bespoke” would be a instance that is tailored to my needs (e.g. “ignore field x in the Eq instance, because it is just a cached value that depends on the other”). The derived instance is not bespoke in that sense. It is more of a stock instance. How about `deriving stock Eq` instead? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/10598#comment:50 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
