		// 1. Why is the value empty?
		// 2. Add a return to the then(), if not, it evaluates to empty.
		// 3. Change to thenRun() to avoid these mistakes of returning data
		// 4. What happens if the computation is taking too long? and we add a timeout?
		// 5. But why a nasty exception, let use a default value now, woot woot!
		// 6. There is also a getNow() which is get whatever you have NOW or return a default value! It's like `timeout:0`
