The only reason you would introduce another closure is to introduce another scope boundary for loading / protecting global objects such as $.

For Example:

    })();

});

I have put together a blog post that might help explaining some of the basic concepts form the point of view of a newcomer to JavaScript, including function scope. http://bit.ly/tLkykX
