Subject: Re: [PHP-DEV] 5.3.8, Why is func_num_args() not working on a Clusure?
From: gergo@gergoerdosi.com (Gergo Erdosi)

Hi,

The function func_num_args() doesn't accept any parameters, so calling =
func_num_args($oClosure) is the same as calling simple func_num_args(). =
That's why it returns 1 instead of 2, which is I think the expected and =
correct behavior.
