[Haskell-cafe] JSON library suggestions?

Hello, Up until now I've been using Aeson, but I've found that its number type isn't going to work for me. I need to use decimal numbers while avoiding conversions from and to Double, which Aeson doesn't allow. There are quite a few more JSON libraries for Haskell, which all appear to use Rational for numbers, so I'm wondering if anyone can recommend one. Thanks, Jeff
