std.range.repeat(1);
I would be very surprised if that's not both bidirectional and infinite.
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.

I do see the lack of actual practical use case, (it doesn't mean none
exists, but few exists) but what does excluding that case brings us ?
