Dmitry. > I like this. Two questions: 1. Can you please clarify what ZEND_TYPE_ENCODE_CLASS_CONST_* is for? Why does this not use the usual encoding for allow_null? Does the compiler not allow casts in initializers or something? 2. Is the use of zend_strings in arginfo of internal functions zts safe? I.e. does the function registration happen per-thread or do we reuse registered functions across threads? If that's the case we might run into issues with non-atomic RCs. Nikita
