Modeling concurrency in Ruby and beyond
summary
Argues that Ruby needs actor/CSP-style concurrency and shows a working Ruby prototype: the agent gem implements Go-like channels and a go keyword, with channels typed and configurable buffer size. Demonstrates a producer/consumer and a worker-pool example with two workers, channel buffer 2, each worker sleeping 1s and returning incremented results — both workers run concurrently without explicit locks. Notes MRI’s GIL limits multi-core gains, recommends experimenting on JRuby/Rubinius/MacRuby, and claims this model is simpler and safer than raw threads.
