How it became like this? Ruby Range class

Years ago, my studies into the Ruby Evolution started with the persuasion that mastering the programming language to express one’s intentions clearly and efficiently may grow significantly by understanding how it evolved and what intentions were put behind its various elements.Moving back through the history of a change of some element of the language exposes a thinking and consensus process that led to API design. It allows one to internalize its functioning, as opposed to just memorizing the cheatsheets.
