#8782: Using GADT's to maintain invariant in GHC libraries -------------------------------------+------------------------------------- Reporter: | Owner: Iceland_jack | Status: infoneeded Type: task | Milestone: 7.10.1 Priority: lowest | Version: 7.9 Component: Compiler | Keywords: Resolution: | Architecture: Unknown/Multiple Operating System: | Difficulty: Unknown Unknown/Multiple | Blocked By: Type of failure: | Related Tickets: None/Unknown | Test Case: | Blocking: | Differential Revisions: | -------------------------------------+------------------------------------- Comment (by rwbarton): Can we keep `foldlOL` and `foldrOL`? The GHC source tends to prefer monomorphic functions over polymorphic ones when the polymorphism is not needed. (See for example Simon's email [http://www.haskell.org/pipermail /ghc-devs/2014-August/006081.html here].) -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/8782#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
