[ruby-core:87144] [Ruby trunk Feature#14473] Add Range#subrange?

Issue #14473 has been updated by shevegen (Robert A. Heiler).


I have no particular opinion (neither pro nor con) on the issue itself.

On the comment:

> [..] this adds another useful Range method, Range#offset (which probably only makes sense for
> numeric ranges), would you accept a new Feature to add this method?

I think it would be best to add a new issue for Range#offset; you can then link into the
issue here too, from that other issue. It makes it easier for other people to comment
on it and, I think, also easier to approve it, if it is useful.

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
~~~
