Issue #14473 has been updated by vo.x (Vit Ondruch).


Why not modify Range#include? to accept Range object. Anyway, there is missing any justification for the RFE.

Hi there,

I'd like to propose a method that returns true when a range that the method gets called on is a subrange of a range passed in as an argument.

Example:

~~~ ruby
(2..4).subrange?(1...4) 
=> true
(-2..2).subrange?(-1..3) 
=> false
~~~
