#15183: Expose the SNat type and the natSing method -------------------------------------+------------------------------------- Reporter: dfeuer | Owner: (none) Type: feature request | Status: new Priority: normal | Milestone: 8.6.1 Component: Core Libraries | Version: 8.2.2 Resolution: | Keywords: 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 dfeuer): goldfire, there are already two singletons for these, but one is uncomfortably buried where we need `unsafeCoerce` to get at it. Since we have built-in support for `Nat`, `Symbol`, `KnownNat`, and `KnownSymbol`, I don't really see the slippery slope. `singletons` should be able to use a newtype instance around the one in `base`. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15183#comment:5 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
