Go doesn't have non-blocking receives anymore. value, ok := <- ch will block, always. Iff the channel is closed, ok will be false, allowing you to distinguish between a zero value sent on the channel, and the zero value you get back if you try to receive on a closed channel. Receiving from a nil channel always blocks. Select statements allow you to check if a channel has had a value sent on it. http://golang.org/ref/spec#Receive_operator http://golang.org/ref/spec#Receive_operator https://groups.google.com/d/msg/golang-nuts/Z63l4LDOlsI/54uTd4x9eiIJ https://groups.google.com/d/msg/golang-nuts/Z63l4LDOlsI/54uT... http://golang.org/ref/spec#Select_statements http://golang.org/ref/spec#Select_statements
