As for your first example:


trait T {
   public function foo() {
      echo <http://www.php.net/echo> "T";
   }}class C {
   use T;
   public function foo() {
      echo <http://www.php.net/echo> "C";
   }}


I think it would sometimes be desirable to allow this, for instance when a
trait has been updated in a framework to adapt to what has become common
practice in classes that uses it in the wild.
( I assume you already get error if function signature is different like in
inheritance? )

So to allow both cases, what about letting people use the final keyword on
functions to signal functions that can not be re declared without alias. Or
better, add a new keyword since final should mean final.

My 2 Euro cents,
