So I tried that initially but my (){ writeln(...) } wasn't 
printing anything in console. Could that be related to stdout 
buffering? The program kept running though.

Read that too, but doesn't seem like the desired behavior I want.


So here's the thing, unlike JavaScript, the D behavior seems to 
be like a while(bool){} has to be placed directly within the 
scope of main. Was thinking as long my while loop in 
setInterval() was running, spawn() will be kept alive.

It seem both vibe.d and arsd have a similar setInterval() 
implementation and they both require using their event loop to 
keep the program alive.

In my case, wanted setInterval() to behave like it's own event 
loop without placing it in a while(bool){} loop in main()
