in thread Perl Cannot Be Parsed: A Formal Proof
The reason for a proof is there had been considerable question about whether Perl 5 was statically unparsable just for practical purposes, or just given present parsing techniques. Adam Kennedy's PPI man page says that the module name Parse::Perl had been reserved in case someone invented a way to statically parse Perl. Opinion shifted to the point where the most people felt certain that no static parser for Perl existed. But I think it's nice to get the issue completely nailed down.
Lack of static parsability is an obstacle for many utilities that deal with Perl 5 code. That's definitely a downside. But it's not the whole equation, and the ability to do Turing-equivalent fiddling at BEGIN time is an upside.
