1.2.107. Cannot Call Static Trait Method Directly

From the migration docs : Calling a static method, or accessing a static property directly on a trait is deprecated. Static methods and properties should only be accessed on a class using the trait.

<?php
 trait t { static public function t() {}}
 a::t();
// OK
 t::t();
 //Calling static trait method t::t is deprecated, it should only be called on a class using the trait

 class a {
    use t;
 }

?>
