#15622: Generalize `E{0,1,2,3,6,9,12}` from `Data.Fixed` -------------------------------------+------------------------------------- Reporter: rockbmb | Owner: rockbmb Type: feature request | Status: new Priority: normal | Milestone: 8.6.1 Component: Core Libraries | Version: 8.4.3 Resolution: | Keywords: base, | Data.Fixed Operating System: Unknown/Multiple | Architecture: | Unknown/Multiple Type of failure: None/Unknown | Test Case: Blocked By: | Blocking: Related Tickets: | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by Ashley Yakeley): Regarding representation type, the performance of the time library, as well as ease of serialisation, might be improvable if `DiffTime` and `NominalDiffTime` (which wrap `Pico`) were represented with 128-bit integer type rather than `Integer`. See https://github.com/haskell/time/issues/80. That said, I'm not feeling a lot of pressure for this at the moment. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15622#comment:23 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
