Bug description:Calling traits directly with static properties/methods
Description:
------------
The documentation for traits indicates that "it is not possible to
instantiate a Trait on its own", but I have noticed that a trait can be
called directly if it has a static property or method, as per the below
example. Is this intended behavior? Or should traits be restricted from
being called directly? I was under the impression that traits cannot be
called directly per the documentation. If not, is there a way to prevent
traits from being called directly as in the below example?
Test script:
---------------
<?php
trait t1
{
public static $a1 = 'test1';
public static function test()
{
return 'test2';
}
}
echo t1::$a1."\n";
echo t1::test()."\n";
Expected result:
----------------
Fatal Error that traits cannot be called directly.
Actual result:
--------------
test1
test2
