When I began learning Ruby, this was one of the first exercises in the first chapter of the book I was using. They had you write 3.minutes, 3.hours, 3.seconds, etc. I can find the book if needed. It may be true that strong ruby developers likely will not do this, but then why teach bad practices to beginners?
