On a more upbeat note, instead of doing an comparison/contrast article with Perl v. Java, why not pick an interesting feature of Perl6 and write up a tutorial on how to best use it? Some ideas...

• The Perl6 Grammar Engine: The Cure For All your Parsing Ailments
• Macros. Done Right.
• Hyperactive Hyperoperators
• Junctions For The Rest Of Us
• Autothreading, Autothreading, Autothreading.
