Put the following into a JavaScript file.

The line with the comma operator will produce an error:
Syntax error on token ",", ; expected

var 
	// Will speed up references to window, and allows munging its name.
	window = this, // error here
	// Will speed up references to undefined, and allows munging its name.
	undefined;

(The above is a simplified version of the jquery-1.3.2 initialization.)
