As I sometimes use Perl, I decided to read something about it. And Higher-Order Perl by Mark Jason Dominus was looking interesting. The book is really nice, it shows that Perl can be kind of a functional programming language and that it’s possible to implement almost every feature from other languages in Perl. Also, after reading the book, I think there’s copious amount of ways to shot yourself in the leg in Perl.
The problems in the book are interesting and a bit challenging, so I think it can be worth reading even for people who don’t work with Perl.
