Hello, how to exit from loop on keyboard button pressing? I see two ways: catch InterruptException or this:

```julia
function main_loop()
	println("Press 'Enter' to stop.")
	task = Threads.@spawn readline(stdin)
    while true
        if istaskdone(task)
            println("stopped.")
            return
        end
        println("working...")
        sleep(1)
    end
end

task = errormonitor(@async(main_loop()))

wait(task)

```

maybe something else?
