Well, nobody's perfect and even experienced developers make mistakes.

While I can agree, that resources should have been objects and even the resource type should not exist, this is what we have to live with. Objects DO have __toString() method (and you cannot use an object as a key without implementing this method in 5.2+), but resources are different. So I would actually change the E_STRICT error to E_NOTICE, as it doesn't make much sense to me to use an internal resource identifier as a key. This internal ID might be reused or another resource with different ID might exist pointing to the same physical resource (connection, structure etc.).
