  __X accessors explanation:

if we have __get and property that is not part of the properties array is
  requested, we call __get handler. If it fails, we return uninitialized.

if we have __set and property that is not part of the properties array is
  set, we call __set handler. If it fails, we do not change the array.

for both handlers above, when we are inside __get/__set, no further calls for
  __get/__set for this property of this object will be made, to prevent endless
  recursion and enable accessors to change properties array.

if we have __call and method which is not part of the class function table is
  called, we cal __call handler.
