Thanks for raising that

	I definitely mean "just for Haskell 98"

I am not trying to say anything about Haskell-beyond-H98.  In fact I
have always personally thought it was wrong to have Float/Double/Ratio
in Enum at all, but the majority view was otherwise a couple of years
ago (for H98).  But for post-H98, the field is wide open.
