The advantage I see is that this will play great in also deconstructing collection like things like Array, Slice and Tuple. This is already familiar to python and ruby users. 

Part of the aim is to avoid less easily discovered custom syntax; the point of the proposal is that there's no need for a special syntax just to support variadics as attributes already exist, plus they're more descriptive about what they do and easy to look-up.
