summary
Compares concrete behaviors: shows CSP concurrency implemented with channels and goroutines, builds an iterator/reduce pipeline that runs and composes, measures a vector-swap at ~8ns on a netbook using gotest benchmarking, demonstrates type inference, interfaces and embedding, exposes raw memory via unsafe package and reflect to turn strings and slices into byte buffers, uses CGO and shows how channels and goroutines coordinate without OS threads.
