Description:
------------
Dont speak english. All in example code.

Test script:
---------------
<?php

trait T {
    abstract static function values(): array;
}

class B {
    use T;
    static function values() {
        return 'Worked!'; // string, not array
    }
}

echo B::values(); // print: Worked!

abstract class B {
    use T;
}

class C extends B {
    static function values() {
        return 'Don\'t worked';
    }
}

echo C::values(); // Fatal Error: Class D contains 1 abstract method and
must therefore be declared abstract or implement the remaining methods
(C::values)
?>
