Class Method Details

.setup(base) ⇒ Object

Experimental and currently not used method_added hook approach protecting against method_added overrides that are not calling super (hopefully, there is no such code in the wild).

Since method_added hook is idempotent, there would be no harm done even if overridding method_added actually had super call and Konstructor’s hook would be called twice as a result of this.
