The point is attaching meta info to values which aren't pointless. Say:

    weight = 42 /* pounds */;

It's kinda like types, but without the type checks. I'm not purely sarcastic, because boxing values within objects so they have a type has drawbacks.

That said, there are better way of typing values without boxing them.
