What do you think? Since it's what Array does (`rb_ary_count `), it would make sense to do the same in `set.rb` IMHO. ---------------------------------------- Bug #16026: `Set#count` performance issues https://bugs.ruby-lang.org/issues/16026#change-80150 * 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:
