Enum, Bounded, and Arithmetic Sequences

Even though enumFromThenTo is useful for Integral types and Rational?

   [1,3 ..]
   [0,1/2 .. 10] :: [Rational]

The only problems with enumFromThenTo come from providing Float and Double 
instances (and are the same problems encountered with providing Float and 
Double instances for enumFrom).
