	//		the original function is reached, at which point the underlying
	//		function (func) is called in the scope thisObj with all of the
	//		accumulated arguments (plus any extras) in positional order.
	// examples:

	//					dojo.debug.apply(dojo, arguments);

	//			tmp("blah", "this is superfluous");
	//			// debugs: "arg one thinger blah this is superfluous"
	//			tmp("blah");
	//			// debugs: "arg one thinger blah"
	//			tmp();
	//			// returns a function exactly like tmp that expects one argument
	//
	//		other intermittent functions could be created until the 3
	//		positional arguments are filled:
	//
	//			tmp = dojo.lang.curry(foo, foo.bar, "arg one");
	//			tmp2 = tmp("arg two");
	//			tmp2("blah blah");
	//			// debugs: "arg one arg two blah blah"
	//			tmp2("oy");
	//			// debugs: "arg one arg two oy"
	//
	//		curry() can also be used to call the function if enough arguments
	//		are passed in the initial invocation:
	//
	//			dojo.lang.curry(foo, foo.bar, "one", "two", "three", "four");
	//			// debugs: "one two three four"

		//	IE 5.5 SP2:
		//	back button behavior is macro. It does not move back to the

		//	that the iframe is the correct way to capture the back button in

		//	Don't test this page using local disk for MSIE. MSIE will not create

		//	The XML served back from the XHR tests will also not be properly

		//	server to test in that browser.
		//	IE 6.0:
