Ruby.inspect
summary
Shows concrete Ruby internals and tools: introduces generational garbage collection (RJGC) that speeds marking up to ~50× and yields ~10% app gains, and symbol GC that lets dynamically created symbols be reclaimed; demonstrates TracePoint with binding objects to count deep recursive calls (tarai) and inspect parameters, and uses object_space.dump plus object-allocation tracing to build interactive graphs of object reachability that actually work.
