Perl is very good for mission-critical large-scale projects together with rapid prototyping. It was created by Larry Wall. It allows you to get away with many bad habits, not only in terms of program layout but also by using inefficient or confusing programming practices. Because it has been around for much longer than Python, there are a great many more modules available for you to use.
