Communicating sequential processes CSP 通信顺序进程 CSP writing to a file by name (process, Erlang) vs. writing to a file descriptor (channel, Go)

在声明和包的设计方面，Go 语言受到 Pascal、Modula 和 Oberon 系语言的影响；在并发原理的设计上，Go 语言从同样受到 Tony Hoare 的 CSP（通信序列进程 Communicating Squential Processes）理论影响的 Limbo 和 Newsqueak 的实践中借鉴了一些经验，并使用了和 Erlang 类似的机制。

CSP 通信顺序进程 

C.A.R.Hoare 1979

CSP是一种用来描述并行系统交互模式的形式语言，最早由C.A.R.Hoare(1934-)在其1979年的一篇论文中提出。

CSP对并发编程语言的设计有深远影响，受其影响的编程语言包括Limbo和Go等。

Distinction

Go is the latest on the Newsqueak-Alef-Limbo branch, distinguished by first-class channels.

Erlang is closer to the original CSP, where you communicate to a process by name rather than over a channel.

The models are equivalent but express things differently.

Rough analogy: writing to a file by name (process, Erlang) vs. writing to a file descriptor (channel, Go).
