Weird Ruby
summary
Showcases concrete oddities: ENV is an Object that syncs with the process environment, numeric literals beginning with 0 are octal, modifier-if collides with number literals, and string successor behavior produces surprising ranges and version sequences. Notes language changes: class variables behave differently in Ruby 3 and constants can be reassigned with warnings. Mentions tooling with numbers: RuboCop hits 424 million downloads, celebrates 12 years and adopts a super‑fast parser, and several examples demonstrate which tricks actually work and which explode.
