Re: [Hat] Hat bug report: Ambiguous occurrence `List'

I wrote:

The following wrapper: foreign import haskell "Prelude.toRational" toRatWord8 :: Word8 -> Rational is the culprit.

I've now found a reasonable workaround and checked it into CVS. Happily, there is no need to attempt to construct a traced Rational primitively - we can do it in plain Haskell code instead: instance Real Word8 where { toRational x = toInteger x % 1 } Regards, Malcolm
