----------------------------------------
Feature #13562: Use a sized enumerator with #yield_self
https://bugs.ruby-lang.org/issues/13562#change-64849

----------------------------------------
The #yield_self Enumerator instance always has a #count of `1`. I think it might be nice to provide a lazy #size of `1` to match the #count for parity.

Currently:

~~~ ruby
42.yield_self.count #=> 1
42.yield_self.size #=> nil
~~~

I propose:

~~~ ruby
42.yield_self.count #=> 1
42.yield_self.size #=> 1
~~~
