I've been digging more into this:
http://svn.php.net/viewvc/php/php-src/branches/PHP_5_3/Zend/zend_builtin_fun
ctions.c?r1=307522&r2=312904&pathrev=312904

From what I understand, this patch is only place where is_a() all of sudden
starts accepting a string.
Btw the documentation has never been updated:
http://php.net/manual/en/function.is-a.php

It seems unintentional, the patch tries to fix a bug but introduces a new
'feature'. Should it be reverted?
