Implicit type conversion of array value

If you upsert(insert) an PHP array into bucket and retrieve it then the values aren't same.

For example,

$this->bucket->upsert('testdoc', array('name'=>'Frank'));
$res = $this->bucket->get('testdoc');
var_dump($res->value);

(output)
object(stdClass)#20 (1)

README should be fixed also if this is intended behavior.
