Larry Wall originally created Perl while a programmer at Unisys. He now works full time guiding the future development of the language as a researcher and developer at O'Reilly Media, Inc.. Larry is known for his idiosyncratic and thought-provoking approach to programming, as well as for his groundbreaking contributions to the culture of free software programming. He is the principal author of the bestselling Programming Perl, known colloquially as "the Camel book."
"Why should I buy this book? Well if you use Perl and are working on the 3rd edition and other works of the same age you are missing out on more than a decade of improvements to the Perl language. Just think of how much more productive you will be if you stop having to type messy constructs like "$x = 3 unless defined $x" and instead say "$x //= 3;"?"
--Martin Houston, FLOSSUK
"This edition offers something for everyone; the novice is introduced to the basics, the intermediate acquires new knowledge or re-evaluates that already in possession filling in the gaps, while the advanced one is getting a tour through all the new language features up to 5.16."
--Nikos Vaggalis, iProgrammer
