Example of using getFunctionCalledName to create dynamic getters and setters

//callednamedemo.bx
component
{
    variables.x1 = 1;
    variables.y1 = 2;

    function init() {
        return this;
    }

    function get() {
        var name = getFunctionCalledName();
        return variables[mid(name,4,len(name)-3)];
    }

    function set(value) {
        var name = getFunctionCalledName();
        variables[mid(name,4,len(name)-3)] = value;
    }

    this.getX1 = get;
    this.getY1 = get;
    this.setX1 = set;
    this.setY1 = set;
}

	o = new callednamedemo();
	// shows *real* methods get(), SetX1() and getY1(), etc.
	writeDump( o );
	o.setX1( 10 );
	o.setY1( 20 );
	writeOutput( o.getX1() & "<br>" ); // 10
	writeOutput( o.getY1() & "<br>" );
