That might make sense if there were a well-defined algebra of
range objects, but there isn't. For example, concatenating the
sequences represented by two ranges with different step sizes
results in a sequence that can't be represented by a single
range object.

Also I can't remember seeing a plethora of use cases for
comparing range objects.
