Do infinite bidirectional ranges make any sense?

Nice. I'm sure there are mathematically-motivated bidirectional infinite 
ranges that are more interesting than the constant range. However, I 
think few, if any, would be of practical interest. We could and should 
probably proceed with the simplification that any bidirectional range 
must be finite.
