Does it *really* make sense for PHP? What if that parent class 'Animal' from your example introduces a constructor that accepts, say, both $owner and $what as mandatory arguments? parent::__construct() call in a descendant will appear broken (unintentionally, I suppose), won't it?

If you introduce a mandatory parameter to *any* function, method, or constructor, existing calls to that function, method, or constructor will be broken. A class with no defined constructor already behaves as if its constructor had no arguments when using "new", so introducing a constructor with mandatory arguments is already a breaking change. -- Rowan Collins [IMSoP]
