Time for action – Assigning from Dynamic variables

You can assign the content of any Dynamic variable to a variable of any type. Indeed, we generally say that the Dynamic type can be used in place of any type and that a variable of type Dynamic is indeed of any type.

So, with that in mind, you can now see that you can write and compile this code:

class DynamicTest
{
   public static function main()
   {
      var dynamicVar : Dynamic;
      var year : Int;
      dynamicVar = "Hello";
      year = dynamicVar;
   }
}

So, here, even though we will indeed assign a String to a variable typed as Int, the compiler won't complain. But you should keep in mind that this is only at compile time! If you abuse this possibility, you may get some strange behavior!
