[ruby-core:114746] [Ruby master Feature#19839] Need a method to check if two ranges overlap

Issue #19839 has been updated by ko1 (Koichi Sasada). I'm not sure what `(n...n)` but on AS definition, the following code returns true. ```ruby p (1..2).overlap?(2...2) #=> true p (2..2).overlap?(2...2) #=> true p (2...2).overlap?(2...2) #=> true ``` is it intentional? ---------------------------------------- Feature #19839: Need a method to check if two ranges overlap https://bugs.ruby-lang.org/issues/19839#change-104582 * 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/
