Keynote: Ruby Typing
summary
Announces a concrete plan for Ruby’s type story: Ruby 2.4 unify Fixnum and Bignum into a single Integer class and adds Unicode-aware case conversions; Ruby 3 aims for soft typing (behavior-based types) that infer anonymous structural types from code and from running tests to build a type database, trading 100% coverage for practical static checks (targeting roughly an 80% compile-time catch rate). Also promises performance and concurrency goals: “three times faster” and real concurrency, with tooling and gem-shared type data to bootstrap adoption.
