Function declarations attached to block scope? #126

Open ivanbacher opened 6 years ago

ivanbacher commented 6 years ago

Say we have the following code:

{
    function aa() {

    }

    var zz;
}

function bb() {

}

which produces the following scope tree:

0: GlobalScope
1: BlockScope
2: FunctionScope
3: FunctionScope

However, if we take a look at the variables array from the global scope object:

we can see that only two variables belong to the global scope, zz and bb. Should aa not also belong to the global scope as it gets hoisted?
