$_=get_class_methods(@new phar);die($_[70]);
IMO, that one was pretty obvious (took me 10 minutes after first look).
I did a quick google search and observed that there were a lot of class having valid() as method... An coincidentally get_Class_methods()
was in the string. After extracting that one, no issues anymore.
