State of the Ruby
summary
Ruby 2.0 arrives with concrete changes: copy-on-write GC reduces Unicorn memory duplication (claim: shared resident pages increase; no app numbers shown because a Rails exception prevents running 2.0), utf8 default literals make file literals Unicode by default, keyword arguments formalize trailing-hash options, refinements are lexically scoped but experimental (demo shows warnings and a symbol-to-proc edge case that breaks), Enumerable#lazy enables infinite pipelines and big-file lazy reads (demos succeed), and module prepend cleanly replaces many alias_method_chain patterns.
