[PATCH] Namespace Patch, Beta 2

Classes that had uppercase letters were not being handled properly in namespace imports. The attached patch has this fix (thanks Maxx!). Also, the attached patch includes the default behavior of resolving simple-imported class names to their file paths (ns:class1 being looked up as ns/class1(.inc or .inc.php). I have a couple of questions, though: 1) I asked this before, but it wasn't answered: is there any reason why .php is not a default extension for spl_autoload? 2) Right now, you have to use the autoload_import_class function for namespace imports so that the class names are properly found. This function can be eliminated if there was a way for me to get the last inserted element in the class_table. Can I just simply call zend_hash_internal_pointer_end_ex on class_table and get that end element, assuming that this was the last element that was inserted? Or is the order in which items are inserted into a hashtable undefined? Regards, Jessie
