[ruby-core:114855] [Ruby master Feature#13933] Add Range#empty?

21 Sep 2023

      Issue #13933 has been updated by Dan0042 (Daniel DeLorme).

It was an ad-hoc example that just seemed to me like it should return true.

As to how to define it... maybe we can say that numeric ranges are equivalent to `begin == -Float::INFINITY` if beginless, and `end == +Float::INFINITY` if endless. Then it would be like saying `(k...k).empty?` with `k == -Float::INFINITY`

Range already responds to #size. It would be nice if it also responded to predicate #empty? :-)
