Issue #16026 has been updated by byroot (Jean Boussier).


> Maybe it's worth considering, #count with no arguments can invoke #size. 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?
