The two chapters on object orientation are great. It really
increased my abiliy to create classes in perl. Good examples
and comparison to other languages (Python, Tcl, Java and
C++).

The book gave me a deeper look at perl internals. It's
very good to know when trying to write better and faster
code. I could never guess it was that easy...

Seeing so much advanced code made my fears go away and now
I have the courage to take full advantage of perl strength!
