#1830: Automatic derivation of Lift -------------------------------------+------------------------------------- Reporter: guest | Owner: | RyanGlScott Type: feature request | Status: new Priority: normal | Milestone: ⊥ Component: Template Haskell | Version: 6.8.1 Resolution: | Keywords: Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Revisions: Phab:D1168 -------------------------------------+------------------------------------- Comment (by simonpj): I'm not dead set against this (adding new auto-derived classes doesn't interact with anything), but it does impose a little extra maintenance burden to keep it all working and you can get nearly the same behaviour with a (perhaps enhance) `th-lift` library. It would seem more persuasive if there was more than one advocate for it. Is there a large constituency of TH users who will benefit from this? Data from Hackage might be illuminating... how many `Lift` instances exist? -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/1830#comment:14 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
