I'm Java/C# programmer for many years .. when I also inherited 1000's of lines of production Perl code.So like most languages, once you get comfortable with the syntax, reading the seminal books, you start to build your toolboxand then rely on "code snippet" books to refine ideas, or get deeper into more specialized aspects of the language when the project requires it.I can't even remember how I found your link .. but from the myriad of Perl ones I cycle through ... your books are not unlike the way I try to organize snippets, around language features, and applications .. but yours are much more complete, and thorough. I'm continually amazed at the power of applying the Perl scalars, lists, and hashes model to any problem. I remember back in the day when Larry Wall won a Dr Dobbs award, and I wondered what the hoopla could possibly be about, after all I was an aspiring high level language programmer, how hard could scripting be? .. its now, many years later that I can now say that I understand... Your books, taken as a whole, are probably the best snippet based collection that I've seen for Perl .. Can't wait for the hash addition.If you're still in the Perl space, it would be cool to see some snippets based on more functional aspects, modules, and dynamic code blocks, which is where I tend to take my Perl code currently...

Just a reply to let you know that I appreciate that you provided a free download of your perl book ...Next in line was the question of just how the product differed from any other book or website for usefulness. I purchased the $10 book, and am still looking it over now. I really like the concept of a list of 'how-to's" that will hopefully save me some time looking up such items on the internet.
