Thanks for the tip about the book. I downloaded it and am finding it very helpful. A few quick comments --
It would be helpful to use plain single quotes in the code fragments instead of curly single quotes.
Instead of including the basics of Perl in the book (there are many other books for that, and the concepts haven't changed that much anyway), it might be more useful to concentrate on comparing P5 to P6, showing equivalent code in both versions, with new, P6-specific idioms.
