Issue #19839 has been updated by shouichi (Shouichi KAMIYA). Thank you for your feedback.
I've made several helpers for this exact same problem, as well as a `Range#merge` in the past.
Yes, `Range` class can have methods such as `Range#merge` but I wanted to start small and see what happens.
What do you expect when it is called with a non-Range object, `TypeError`, same as cover? or something else?
Yes. Raising TypeError seems correct. I'm going to fix the PR. ---------------------------------------- Feature #19839: Need a method to check if two ranges overlap https://bugs.ruby-lang.org/issues/19839#change-104154 * Author: shouichi (Shouichi KAMIYA) * Status: Open * Priority: Normal ---------------------------------------- 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 ``` -- https://bugs.ruby-lang.org/
