This will allow for testing if a class extends or
implements another code unit, anywhere in the inheritance tree.

Do we really need to check both? Both do the same, except that is_a() also returns true for the class itself (like is_a(A::class, A::class)), AFAIK, so is_subclass_of() should never be called.

unfortunately, is_a doesnt check for interface implementation, and is_subclass_of doesnt check for same class. :(

I think it does: https://3v4l.org/91Yt8

AFAIK, is_a does the same as instanceof (and it is even more powerful, since it can check string class names and not only instances, if the third parameter is true).
