| Breaking code is:
| "class XML a where toXML :: a -> XML"
| 
| result is:
| Compiling Main ( /home/shae/src/haskell/ProtoWebPublish.hs,
interpreted )
| ghc-6.4.20050303: panic! (the `impossible' happened, GHC version
6.4.20050303):
| 	ds_app_type Main.XML{tc r1BX} []
| 
| Not sure if this is already a known bug.
