Channels require goroutines. `<-variable` blocks the goroutine it is in and waits for another goroutine to do the opposite, being `channel <- value` You can't use channels without goroutines, and really, the main purpose for goroutines is exactly about moving things through channels.
Goroutines probably are the most confusing and error prone part of Go, as it can be very hard to see who is loading the channel and who is not, and if they are in the same goroutine it won't work, as one part of it waits for the other part that will never start running, because it already is, and is blocked. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
