Subject: [ruby-core:87944] [Ruby trunk Feature#14473] Add Range#subrange?

Issue #14473 has been updated by znz (Kazuhiro NISHIYAMA).


How about `Range#{<,<=,>,>=}` like `Hash#{<,<=,>,>=}` for method names?

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
~~~
