Block-Scoped Functions code is wrong.

[Leon]

This is wrong. That code depicts function-scoped functions. It should actually be this:

{
    function foo() {...}
    foo();
    {
        function bar() {...}
        bar();
    }
}

ES5:

function foo() {...}
function bar() {...}
{
    foo();
    {
        bar();
    }
}

Good catch. Thanks for the hint. I've revised the stuff and now showcase both Function-Scoped Functions and Block-Scoped Functions. How it is correct now.
