[BUG] Local functions persist in other class-level functions

[Starexify]

In polymod if we add a local function like:

override public function onCreate(event:ScriptEvent) {
  var value = 1;
  function myLocalFunction(i) {
    return value + i;
  }
  trace(myLocalFunction(2));
}

We could call it in a separate function in the class like so and it would work:

override public function onStateCreate(event:ScriptEvent):Void {
  trace(myLocalFunction(2));
}

And for some reason it would work.
Not sure if this should be allowed, but it seems like a bug to me since haxe doesn't allow this.
