Context: http://127.0.0.1:3999/concurrency/1

In concurrency/1 (Goroutines), commenting out line 17 say("hello") also stops the go say("world") from doing anything. The program exits before any worlds are said, yet without commenting out line 17 it seems to wait for all goroutines to finish before exiting.
