Sorry for not having IE7 currently available.
Could anyone check if FunctionExpression bug is fixed in IE7 beta or
stay the same (it was once confirmed by IE team, but did they do
anything?)
A minimum test case:
<html>
<head>
<title>bug test</title>
<meta http-equiv="Content-Type"
content="text/html; charset=iso-8859-1">
<script>
var f = (function foo(){});
window.alert(typeof foo);
</script>
</head>
<body>
</body>
</html>
Correct value: "undefined" (FF, Opera)
IE6 reports: "function"
