Alternatively, use Nat directly?
{{{ newtype Fixed (n :: Nat) = MkFixed Integer }}}
Yeah, looks nice. But one should scan Hackage again to make sure that no one derived `HasResolution` instances for his own types. Replying to [comment:25 Ashley Yakeley]:
`Nat` is just a wrapper for `Integer`, isn't it? As opposed to `data Nat = Z | S Nat`?
Yes. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/15622#comment:26 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
