I'd object to it returning something that resembles a list too closely, but I could live with str(range(3)) return <0, 1, 2>. We should probably have a cutoff so that if there are more than 6 values it'll show the first 3 values, then dots, then the last 2 values. (The cutoff would be computed so that '...' always represents at least 2 values.
