// this code doesn't work as expected in firebug, due to the way it eval's code
// (showing that http://www.slideshare.net/douglascrockford/crockford-on-javascript-act-iii-function-the-ultimate/9 isn't quite true)

foo(); // hello

function foo() {
	alert('hello');
}

bar(); // error 'bar is not a function'

var bar = undefined;
bar = function bar() {
	alert('hello');
}
