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

I have just checked into CVS a tracing version of Data.Word.  It compiles, but
I haven't tested it.  Currently it provides instances of
    Eq, Ord, Bounded, Num, Enum, Read, Show
but omits instances of
    Real, Integral, Ix
because of tedious errors I haven't tracked down.  If you need those
instances, I'll look into it further.
