Lazy enumerators were added in Ruby 2.0 back in 2013: https://www.ruby-lang.org/en/news/2013/02/24/ruby-2-0-0-p0-i...

Thanks. I have not had occasion to use them so was curious if they were a newer or just less known feature.

I’ve used them quite a bit since they were introduced. Still, the plural of anecdote isn’t data, so I couldn’t tell you how widespread their usage is.
