Description:
------------
I have a trait for translations that contains a public function _().
I clone an object that use this trait.

Expected : Object or trait method __clone() is called by PHP if present.
Actual : __clone() method is not called, _() method is called by PHP instead

This does not occur when the class itself have a _() method, this seems to be related to traits.



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

trait MyTrait {
  public function _() {
    throw new RuntimeException('Should not be called');
  }
}


class MyClass {
  use MyTrait;

  public function __clone() {
    echo 'I\'m working hard to clone';
  }
}


$instance = new MyClass();
clone $instance;

Expected result:
----------------
should display "I'm working hard to clone"

Actual result:
--------------
PHP Fatal error:  Uncaught RuntimeException: Should not be called in [...]clone_poc.php:5
Stack trace:
#0 /home/pbarroca/workspace/clone_poc.php(20): MyClass->_()
#1 {main}
  thrown in /home/pbarroca/workspace/clone_poc.php on line 5

Yes, traits only, in case the method name matches any prefix of that length of a magic method...
