Store ColdFusion function in ColdFusion variable

I was just making some testing in ColdFusion. I found some interesting thing. we can store our ColdFusion function in a variable like we are assigning value to some variable and using the variable we can call the function.

Example:

	<cfscript>
	//function defined in cfm page which will add two number and will return the value
	function addTwoNumber(num1, num2) {
	return num1 + num2;
	}
	varriable.x = variables.addTwoNumber; //Function defined in this page is assigned to the variable x
	writeOutPut("Call to addTwoNumber : " & varriable.x(10,12)); //Function call to AddTwoNumber by using variable
	variables.y = createObject("component", "test").addTwoNum; // Function defined in test.cfc is assigned to variable y
	writeOutPut("<br/>Call to addTwoNum :" & variables.y(10,20)); //Function call to addTwoNum by using variable
	</cfscript>

test.cfc

	component {
	public function addTwoNum(num1, num2) {
	return num1 + num2;
	}
	}
