Towards a Higher-Level Language
summary
Argues Ruby remains the highest-level mainstream language and proposes a concrete redesign: remove legacy primitives, kill symbols and floats by using frozen/GCed strings and an arbitrary‑precision decimal type; replace nil with optionals and typed arrays to avoid null errors and enable optimized indexing; make methods return method objects, add method overloading and a single unified function syntax, and provide higher‑level concurrency primitives instead of raw threads — several Ruby 2.1/2.2 behaviors (symbol GC and frozen literals) motivate these choices.
