Ruby Next: make old Ruby quack like a new one
summary
Claim: Ruby Next backports Ruby 2.6/2.7 features so older Rubies behave like newer ones by combining refinements for APIs and a transpiler for syntax. It uses Parser and Unparser, hijacks require at runtime or transpiles at build for gems, and ships transpiled files plus a small runtime shim. Tests come from Ruby Spec and Ruby's own tests. Pattern matching transpiles to if/else and can be as fast or faster; startless ranges and one-line pattern matching remain unsupported.
