Almost every chapter is limited to 10 or 12 pages, yet is still able to cover complete topics. This works great for learning a brand new concept or idea in a single sitting. Each chapter ends with 2 or 3 practice problems, proving quality not quantity is the way to go. Each of these practice problems also state how long it is expected to take. I especially enjoyed the 5-15 minute exercises, which reinforced concepts just read, but weren’t overwhelming.

As with other O’Reilly books, Intermediate Perl teaches through examples. The book builds on similar problems throughout. The examples are quick and concise. Humor and Pop references make parts of the book read like a good novel. If you’ve used Perl before, and are interested in more advanced concepts and efficient programming, look no further.
