Issue #16026 has been updated by ioquatix (Samuel Williams). I was okay with changing my implementation to use `#size` - which is what I've done. However, I don't think there is anything wrong with optimising this use case if it doesn't add any overhead to existing use case. Because `Array` does it too, it makes me think it's not a completely stupid idea. ---------------------------------------- Bug #16026: `Set#count` performance issues https://bugs.ruby-lang.org/issues/16026#change-80677 * Author: ioquatix (Samuel Williams) * Status: Open * Priority: Normal * Assignee: knu (Akinori MUSHA) * Target version: * ruby -v: * Backport: 2.5: UNKNOWN, 2.6: UNKNOWN ---------------------------------------- `Set#size` is O(1), but `Set#count` is O(N). I would like to add `alias count size` to `class Set` Is it okay? -- https://bugs.ruby-lang.org/ Unsubscribe: <mailto:ruby-core-request@ruby-lang.org?subject=unsubscribe> <http://lists.ruby-lang.org/cgi-bin/mailman/options/ruby-core>
