[ruby-core:86169] [Ruby trunk Feature#14473] Add Range#subrange?

Issue #14473 has been updated by owst (Owen Stephens).


Are there any further thoughts on my latest patch? Based on the discussion above, I think I should rename the added methods: `s/set/range/` and perhaps also prevent the "bad performance" cases where either range has `exclude_end?` true and `linear_object_p` false?

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
~~~
