Hi,

Is this intended not being able to give a new name to a method even in
case of no conflict?
In the following example, I try to provide the name "sayIt"
additionally to "saySomething" from trait "Hello":

<?php
trait Hello {
   public function saySomething() {
     echo 'Hello';
   }
}

class MyHello{
   use Hello {
         Hello::saySomething as sayIt;
   }
}
?>

The following error message is shown while running it:

Fatal error: Failed to add aliased trait method (sayIt) to the trait
table. There is probably already a trait method with the same name in
%s on line %d

The error message might be misleading even if it should only be
available in case of conflict.

Regards,

Thanks for catching this, it is a bug.
It works without the Hello:: part and it should also work with the Hello::.

Fixed with the following commit: http://svn.php.net/viewvc?view=revision&revision=305512

Best regards
Stefan
