Example:
average :: Int -> Float
average n = fromInt ( sum n ) :: Float / fromInt n :: Float
It works only in Hugs November 2002

I'm too lazy to check the standard, so I'll just assume Hugs was
wrong. I think the solution is to use "fromIntegral" instead. GHCi
also has "fromInteger", although I'm not quite sure why we need this
in addition to "fromIntegral"? (Possibly because it is a member of
Num, and it would break too much code to remove it)
