Description:
------------
Why not adding something like this in classes:

public $array:Array;
private $bool:Bool = false;
protected $number:Number = 40;
var $string:String = 'a text';

This is like forcing a variable into a bool, array, number etc.
This should be pure for classes only.
Assigning an array value to like a :Number, will cause a notice error.

This is usefull for 
1. Debugging
2. accessing public values
3. If you are working with more than 1 person, your class won't get messed up.
4. if you use like :Number, and you insert '10', it can force it into a number.
