It's for `nil`, that means begin-less range. ---------------------------------------- Feature #19839: Need a method to check if two ranges overlap https://bugs.ruby-lang.org/issues/19839#change-104657 * Author: shouichi (Shouichi Kamiya) * Status: Closed * 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/ ______________________________________________ ruby-core mailing list -- ruby-core@ml.ruby-lang.org To unsubscribe send an email to ruby-core-leave@ml.ruby-lang.org ruby-core info -- https://ml.ruby-lang.org/mailman3/postorius/lists/ruby-core.ml.ruby-lang.org/
