I hear what you're saying but I'd rather not waste even those two hours ;)

I agree with what @erikpukinskis said but I'll also add that I just like the way they read. It immediately tells me that there is a limited number of potential values that can be put in a place. If I see some arbitrary string then I have to wonder, if only briefly, if any arbitrary string can be plugged in there.

    // What does addTask take? Days of the week?
    // Time-sensitive identifiers like you'd see in moment.js?
    // I guess I'll check the definition or mock out a call to see
    addTask('Sunday', newTask)

    // vs.
    // Ah, it takes a day
    addTask(Day.Sunday, newTask)

It's subtle and not super important but it makes me happy.
