Understanding <- <-in

For newcomers to Golang (like myself) seeing c <- <-chan can be quite confusing. It isn't that channels in and of themselves are confusing, but the seemingly duplicate <- is deceptive. So I broke it down a bit and it really is simple. See this example in a simple channel fanning function.

func fanIn(input1, input2 <-chan string) <-chan string {
 c := make(chan string)
 // This looks confusing, but is actually simple.
 // This is easier to digest if we read from right to left.
 // On the right hand side we have a channel (input1).
 // When that channel gets data (<-input1), pass that data 
 // to the new channel (c <-). So at run time we essentially have
 // c <- "my value"
 go func() {
 for {
 c <- <-input1
 }
 }()
 go func() {
 for {
 c <- <-input2
 }
 }()

 return c
}
