I accept the idea. Take `Enumerable` as initial values. Matz. ---------------------------------------- Feature #17327: The Queue constructor should take an initial set of items https://bugs.ruby-lang.org/issues/17327#change-89906 * Author: chrisseaton (Chris Seaton) * Status: Open * Priority: Normal ---------------------------------------- I often create a `Queue` and then process it with a set of concurrent workers in threads. I end up writing: ```ruby q = Queue.new worklist.each do |work| q.push work end ``` I'd rather be able to write ```ruby q = Queue.new(*worklist) ``` -- https://bugs.ruby-lang.org/
