Why is the compiler not complaining about an additional ',' in Array or Object Initializers?

Using simple type like

class A {
  public int X, Y;
}

with object intializers, one can write

var a = new A { X=0, Y=0 };

But the following is also accepted by the compiler:

var a = new A { X=0, Y=0, }; // notice the additional ','

Same for int[] v = new int[] { 1, 2, };

This looks a bit strange ... Did they forgot to reject the additional ',' in the compiler or is there a deeper meaning behind this?
