ghc: panic! (the 'impossible' happened)
(GHC version 6.10.0.20081007 for i386-unknown-linux):
TcTyFuns.uMeta: normalisation shouldn't allow x ~ x
Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug

where stats.hs is:
mean :: (Num b) => [a] -> (a -> b) -> b
mean set f =
let total = sum $ map f set
mean' = total / fromIntegral $ length set
in mean'
NOTE that i'm not even sure if this code is correct or makes sense, i'm in the middle of growing it.
