The unsigned left shift operator <<< operator$ushl is overloaded for nodes of the type null.

The operator can be used with two Null extending nodes to forward all possible parameters from the right Node to the left Node. This is based on the inheritance of object orientation.

module A(float len) extends Sphere(0.1)
{
	{setShader(GREEN);}
}
 
protected void init ()
[
	Axiom ==> A(1);
]
 
public void run ()
[
	a:A ==> Sphere.($ <<<a); // creates a sphere with the same transformation, Shader and radius 
]
 
public void run2 ()
[
	a:A ==> Box.($ <<<a);// creates a Box with the same transformation and Shader 
 
]
