in thread Perl not BNF-able??

But keep in mind that PPI is just guessing, some of the time, using the most likely parsing, rather than an absolute parsing. So, it's still not formal or official, it's merely workable on most programs. But there's no way to know in the code if it's ever done the wrong thing... you simply get a wrong parse and no indication.
