digitalmars.D.learn - Coexistence of static and unstatic method

I have this class: http://dpaste.dzfl.pl/95990b4e
and would like that this call "Vector2s vec = Vector2s(42, 23);" 
returns a new object and that this call "vec(44, 26)" set the x 
and y coords from the existing object to 44 and 26.
Is that possible?
I try to check if the object is initialize with "if (is(this))" 
but it seems that this is true for static and unstatic methods.

P.S.: Is the conversion with "to" accurate? Sometimes U or/and V 
are the same as T and then it isn't necessary to cast them. 
Checks "to" if that's the case, and then prevents an explicit 
cast?

I've tried different things and that here indeed compiles, but 
does not work as it should/I want.

typeof(this) opCall(U, V)(U x, V y) if (__traits(compiles, { 
this.x = 5; })) {
	writeln("unstatic opCall");
	this.Set(x, y);

	return this;
}

static Vector2D!(T) opCall(U, V)(U x, V y) if 
(!__traits(compiles, { this.x = 5; })) {
	return new Vector2D!(T)(to!(T)(x), to!(T)(y));
}
