Subject: [ruby-core:82959] [Ruby trunk Feature#13933] Add Range#empty?

Issue #13933 has been updated by shan (Shannon Skipper).


Range mixes in Enumerable so you can use #none?.

~~~
('a'..'b').none? #=> false
('b'..'a').none? #=> true
~~~

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