I worked in last a few days with each_with_object method. Every time when I would like to use some method in Ruby I try read documentation one more time and I look on some example of usage. This time I went through APIdock and I noticed that in theirs documentation is missing one very nice example of usage each_with_object method. I tried to add this missing part there, but without success. In meantime when I’m waiting for message from APIdoc support I decided to write short note here about this.
