Do you remember when the range became available through the channel?

In Go, the range operator over a channel has been available since the earliest versions of the language, starting with Go 1.0.

This is a fundamental feature that allows iterating over values received from a channel until it is closed.

Example:

ch := make(chan int)
go func() {
    for i := 0; i < 5; i++ {
        ch <- i
    }
    close(ch)
}()

for val := range ch {
    fmt.Println(val)
}

Thus, range over a channel is a standard and long-standing construct in Go.
