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

Issue #13933 has been updated by marcandre (Marc-Andre Lafortune).
Note that `Range#size` currently returns `nil` for ranges of string, so it's not clear what `empty?` would return for ranges of strings.

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
~~~

I think the semantics between ".none?" is not the same as ".empty?". At
the least the latter appears to be more explicit to me.
But it's also not that important to me personally, I am fine either way. :-)
