You found Larry Wall's Perl book rambling and incoherent? And you a professed book-lover? Are you aware that different book authors have different styles? (Ofc you do.) Or that Perl is a language, a set of creators and authors, and an ecosystem that does not feel the need to toe the line of the conventional, in fact, disregards it in favor of exploring different styles / options / methods? Explain yourself, Sir Noufal, or pistols at dawn in Buckingham Park. Okay, your choice of weapons. I shall come armed with the Camel book, nothing else ;)
