-     A class cannot implement two interfaces that share function names, since
-     it would cause ambiguity.
+     Prior to PHP 5.3.9, a class could not implement two interfaces that
+     specified a method with the same name, since it would cause ambiguity.
+     More recent versions of PHP allow this as long as the duplicate methods
+     have the same signature.
