When you learn a language - Perl 5 in this case - its syntax becomes 'intuitive'. From then on, any deviation from it is unintuitive. It takes a special kind of genius to be both familiar with that language and step outside of it to determine what will be more intuitive to someone who has not encountered the language at all yet, and that's what we have in Larry and Damian. In my classes, people invariably wanted to put @ on the beginning of an array element to begin with. After enough correction, they learned to use $, and adopted the rationalization for it. But most people's first instinct is @. That's why the Llama book doesn't introduce the @ sign for arrays until after its shown the use of $ for scalar elements. Damian and Larry determined that they could remove this small speed bump without any damage to the language. -- Peter Scott http://www.perlmedic.com/ http://www.perldebugged.com/ http://www.oreillyschool.com/certificates/perl-programming.php http://www.informit.com/store/product.aspx?isbn=9780133036268 -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
