Hi Evert,

Don't think so.
You do use aliasing to handle conflicts and in the case of a conflict
there is no oldMethod.

trait A {
  public function foo() {echo 'foo';}
}

trait B {
  public function foo() {echo 'fooBar';}
}

class MyClass {
  use A;
  use B {
    !foo, fooBar => foo
  }
}

The result will be at runtime:

class MyClass {
  public function foo() {echo 'foo';}
  public function foo() {echo 'fooBar';}
}

Here you can't do something like this:

class MyClass {
  use A;
  use B;
}

since eventually there wont be any method in MyClass.
