I needed an intro to Perl, which also let me jump into examples. From the table-of-contents, this book seemed like it would be a good one. However, I found the first chapter so full of errors (especially in the code examples) that it was almost worthless for a Perl newbie like myself.
With Perl especially, it is difficult to know for certain whether a stray symbol in the code samples is a mistake or a subtle construct of Perl. This book's examples are cluttered with such odd mistakes, which really are generally mistakes.
Even worse, there is really inadequate discussion surrounding the code examples to tell exactly why they are presented. Sometimes new constructs actually are introduced in the examples, without explanation surrounding them (or even reference to the later sections where they will be fully explained... which would be fine too).
Very difficult for a beginner, and probably too simple for an expert.
