Is it ok to call non static methods with call_user_func in PHP 5.3?
<p>When I use <code>call_user_func</code> on a non-static method in PHP 5.2 I get a Strict Warning: </p>

<pre><code>Strict Standards: Non-static method User::register() cannot be called statically
</code></pre>

<p>But on PHP 5.3.1 I don't get this warning. Is this a bug in PHP 5.3.1 or is the warning removed?</p>
