What's this?

include_with_range?(value) public

Extends the default Range#include? to support range comparisons.

(1..5).include?(1..5) # => true
(1..5).include?(2..3) # => true
(1..5).include?(2..6) # => false

The native Range#include? behavior is untouched.

('a'..'f').include?('c') # => true
(5..9).include?(11) # => false
