The "this" object accesses the current function context.

{%
	// Functions not invoked on objects have no this context
	function test() {
		return (this === null);
	}

	// When invoked, "this" will point to the object containing the function
	let o;

Test that the context is properly restored if function call arguments are
dot or bracket expressions as well.
