#11135: Migrate more of Data.Functor.* from transformers to base. -------------------------------------+------------------------------------- Reporter: hvr | Owner: Type: task | Status: closed Priority: highest | Milestone: 8.0.1 Component: libraries/base | Version: 7.10.2 Resolution: fixed | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Phab:D1543 Wiki Page: | Phab:D1544 Phab:D1630 -------------------------------------+------------------------------------- Comment (by RyanGlScott): We definitely need to add a lot more `Eq1`/`Eq2`/etc. instances than what are currently provided. I didn't include any instances that weren't from `transformers` in Phab:D1543 to keep the migration simple. Another reason I held off on new instances is that I'd like to be able to derive `Eq1`/`Eq2`/etc. with a new language extension (for which I haven't though a good name yet—`DeriveLiftedClasses` perhaps?) to eliminate a lot of the inevitable boilerplate. If you really need an `Eq1 StableName` instance right now, feel free to submit a patch to Phabricator—but I doubt I'll get around to it until later. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/11135#comment:25 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
