12 Sep 2023

      Issue #19839 has been updated by hsbt (Hiroshi SHIBATA).

Status changed from Feedback to Open

Thanks. Basically, we didn't add new methods from ActiveSupport without performance reason.

Can you describe why we should add `overlap?` to ruby core?

It would be convenient to have a method that checks if two ranges overlap. For example,

```
(0..10).overlap?(5..15) #=> true
(0..10).overlap?(20..30) #=> false
```
