#8165: Use GeneralizedNewtypeDeriving to automatically create associated type families -------------------------------------+------------------------------------- Reporter: MikeIzbicki | Owner: RyanGlScott Type: feature request | Status: new Priority: normal | Milestone: 8.2.1 Component: Compiler (Type | Version: 7.6.3 checker) | Resolution: | Keywords: TypeFamilies Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: #2721 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by goldfire): Just to be clear on the design here: we plan on rejecting the code in comment:14, right? That is, for GND to work with associated types, the last parameter of the class must be mentioned in the associated type LHS. Then I'm on board. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8165#comment:20 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
