It wouldn’t be necessary to make the parser work, but I think we’d want something to make it clear what was intended.  Otherwise, you could write:

	init(a : Int, …) 

when you meant:
	init(a : Int …)

and unfortunate things would happen.  The memberwise keyword also makes it much more clear to the reader what is going on.
