RE: [PHP-DEV] Accept null type hint in C

I tried the "|!O" and that really hoses things. The | gets processed in zend_parse_va_args and removed (spec is incremented), so that "!O" get sent to zend_parse_arg_impl. Inside of zend_parse_arg_impl, the ! gets set to char c and spec_walk gets incremented which makes the check for the null operator fail and also makes the check for arg type check the ! in the switch case. The result is that "unknown" got sent as the parameter to the function. Not sure if this would be classified as a bug, but it doesn't work for trying to accept a null type hinted parameter in C. I'll keep playing around with parameter combinations and see what works.
