Comment (by jacobsantos):

 I recommend not doing it any existing way in WordPress. I die a little
 every time I read WordPress code. It is like, "Do you even OOP?" and the
 answer is no.

  * Use interfaces.
  * Smaller independent classes.
  * Smaller interfaces.
  * Type hint interfaces or check instanceof.
  * Attempt to move away from inheritance and more towards composition.
  * Don't ever, never ever. Never ever? Yes, never ever use static methods,
 unless you are creating a singleton.
  * If the question is, "Should I use a singleton?" The answer is no. If
 the question is, "Are you sure I shouldn't use a singleton?" The answer is
 still no. If the question is still, "I think I should use a singleton."
 then okay, you obviously know what you are doing, so go ahead.
  * Classes should be small.
  * Methods should be small.
  * Views should be in a separate file.
  * Classes should only contain unique code.
