First Perl 6 Book is Out
prostoalex writes "O'Reilly Publishing presented Perl 6 Essentials, the first book to be dedicated to Perl 6, at the beginning of this month. Looking at the table of contents, it hardly looks like a valid replacement for Llama or Camel books. Chapter 1 is available online. The whole book is available to Safari subscribers." I'm sure we'll review it sooner or later.
>> Sure, my const int $var = 27; may look neat (in the same way that, say, Pascal [lysator.liu.se] does), but $var isn't entirely constant, or entirely an integer, it's just a hack which makes it sort of behave like one. The whole thing is an exercise in pseudo-computer science masturbation with little real purpose except to please the managers who dislike the one thing that makes Perl special.
The reason for this is because if you tell the interpreter what sort of data it is, it helps the interpreter do more optimizations with that data. Sure, it's not truly an integer, but at least you're helping the interpreter out but telling it how it can deal with the data.

Of course, there is a lot of features in Perl. 200 ways to do one thing (which couldnt be considered a bad thing), but it's actually really cool, because it lets you stick to your own style more than other languages. Face it, perl should not be used unless you know what you are doing with it. It can get ugly, but it's powerful and can do certain tasks amazingly well, and better than any other language.
Sure, it's bloated.. but the way it's being designed should make it so the bloat doesn't affect the speed or power.
And you won't truly be able to appreciate Perl (especially 6), until you learn all the shortcuts [features] (not all, but..) . There is a lot to learn about the language before utilizing it's full power, but once you master it (if possible with perl), it becomes really fun.
