Concurrency Ideas

anonymous.go

package main

func main() {
	pingchan := make(chan string)
  	// Have a channel per callout group

	go func() {
		result := Sequential()
		pingchan <- result
	}()
	
	// Do the other concurrent calls here
	// ...
	
	// Then receive all the results, may as well be one by one
	received := <-pingchan
	fmt.Println(received)
}

func Sequential() string {
	return "In Sequence"
