Feature #13562: Use a sized enumerator with #yield_self

• Status: Closed
• Assignee: -

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:

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

I propose:

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

I'm not at all sure about my implementation, but here is a pull request with my attempt: https://github.com/ruby/ruby/pull/1615
