What's the point of one-way channels in Go?

Question

I\'m learning Go and so far very impressed with it. I\'ve read all the online docs at golang.org and am halfway through Chrisnall\'s \"The Go Programming Language Phraseboo

Answer 1

Go channels are modelled on Hoare's Communicating Sequential Processes, a process algebra for concurrency that is oriented around event flows between communicating actors (small 'a'). As such, channels have a direction because they have a send end and a receive end, i.e. a producer of events and a consumer of events. A similar model is used in Occam and Limbo also.

This is important - it would be hard to reason about deadlock issues if a channel-end could arbitrarily be re-used as both sender and receiver at different times.
