I think that the online book Exploring Programming Language Architecture in Perl would make a great addition to the Tutorials section, probably in one of the "Miscellaneous Perl Tutorials" or "Other Topics" sections.

It's an excellent (free) book written on a subject which every Perl programmer should probably be at least passingly familiar with (programming languages, parsers, and interpreters, that is).

Another thing that I like about it is that it walks the beginning programmer through the entire process of building a full-featured, large-scale application -- namely a parser and interpreter(it even shows how to write tests!), which is something that many tutorials with their "Hello world" and "Convert Fahrenheit to Celsius" examples do not effectively teach.

Thanks,
