Assignment to multple variables with vector



I have a vector:
	A_0 : [ x, y, z ] $

And another vector:
	q : [ 1, 2, 3 ] $

Using the above, is there an easy way to assign to each of x,y,z the 
values from q?
Something like:
	A_0 ?: q $
	Results in:
		x : 1;
		y : 2;
		z : 3;

What is the ?: operator?
