Perl one-liners are a great way to learn more about Perl -- there is a lot of uncommon syntax that makes some of the more advanced examples more like little puzzles.
However, if you are not familiar with Perl, and fall to the common stigma that Perl is unreadable, I urge you to delve more into the modern Perl community. The community doesn't have the same tendencies towards built-in obfuscation anymore.
Yes, I was just now reading the PDF book excerpt and came to note that there are no quotes in the example as it appears in the book, on page 4. The book looks like a great balance between fun and sheer density of information, a reference book that manages to be a delight to read.

The double quotes are not needed around a and z. (Verified in 5.14, 5.12, and the truly ancient 5.8).
