Messing with channels and goroutines

channels.go

package main

import "fmt"
import "time"

func consume(c chan int) {
    for {
        fmt.Println("sleeping for a second...")
        time.Sleep(1000 * time.Millisecond)
        fmt.Println("consumed:", <-c)
    }
}

func main() {
    c := make(chan int, 2)

    go consume(c)

    c <- 1
    c <- 2
    fmt.Println("now 2 elements are in the buffer..")
    c <- 3
    fmt.Println("if advances to here, spot in buffer opened up for 3")
    c <- 4
    fmt.Println("if advances to here, spot in buffer opened up for 4")
}
