Description:
------------
PHP 7.1.11
Using a function from trait ends up with using wrong function. 



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

trait traitA {
    public function __invoke() {
        echo "traitA\n";
    }
}


trait traitB {
    public function __invoke() {
        echo "traitB\n";
    }
}

class JustAClass
{
    use traitA {
        __invoke as protected hocus;
    }

    use traitB {
        __invoke as protected pocus;
    }

    public function __invoke()
    {
        $this->hocus();
        $this->pocus();
    }

}

$instance = new JustAClass();
$instance();

Expected result:
----------------
traitA
traitB

Actual result:
--------------
traitA
traitA

Or I would it expect to complain that 2nd invoke wasn't imported because of name collision. But that not what you prefer when you giving detail reqirements on under which name function should be accessible.
