The Modern Rubyist: When and How to Use the Latest Features
summary
Shows concrete examples from production code (Mastodon, deod) and demos actual tradeoffs: endless method (Ruby 3.0, makes single-expression helpers clearer and discourages accidental complexity), data class (Ruby 2022, frozen, value-equality objects for packing API responses), hash value omission (2021, enforces consistent naming and benchmarks ~3x faster than using Binding), and pattern matching (creates locals, requires pinning to avoid overwrites, rightward operator raises on mismatch). Recommends experimenting locally and adjusting linters rather than banning new syntax.
