goroutines = (poorly implemented) cheap threads threading (or CSP) is nothing new conceptually. yes, i agree, the go language has popularized a cheap threading implementation but the same design concepts we've applied to unix processes and posix threads apply to goroutines. btw, blocks in ruby and generators in python have existed for many years prior to go.
