This book introduces Perl to both new programmers and experienced ones who are looking to learn a new language.
I don't get it. I mean the two groups are so different than having a single book trying to work for both is just ... I don't know. Learning the first language and learning yet another is very different and by trying to please both groups you run a very high risk of both being too quick for the first group and boring the second to death.
Enoch was right!
