Perl's Extreme Makeover
PurdueGraphicsMan writes "There's an article over at Yahoo! about the upcoming version of Perl (version 6) and some of the new features (RFC list). From the article: "Although Perl 5's expressions are the most sophisticated available and aspired to by other programming languages, "no one pretends for a moment that they're anything but hideously ugly," said Damian Conway, a core Perl developer and associate professor at Monash University in Australia.""
flamebait? I'm a fan of perl, and I hate how it's gone in the shitter. I'm sorry I insulted your girlfriend, but remember, I get mod points too..
"Ummmmmmm, what the fuck is this supposed to mean?
This is only true for newbies. Experienced programmes in any language can figure what stuff means, even if they looking at code they dident write themselvs.
One of the goals of Perl 6 is to make non-trivial projects possible. That's good. The way it's being done is bad. Perl was once a lightweight, extremely flexible language. Now it's become a huge ugly monster. People wanted OO, so a nasty hack was bolted on top to allow some semblance of it. Now this nasty hack is being expanded. Sure, the code's different, but the basic form is the same. Kludge upon kludge upon kludge; I'd much rather have a nice, clean, pure language (and not one with loads of irritating whitespace thank you very much).
The same goes for the syntax. All the switching between $, @ and % is really irritating (ask a newbie how to get at the length of the keys array of a hash inside a hash, for example), and the changes proposed for 6 are just making this worse -- it seems that Larry, in his infinite wisdom, wants to prefix every data type with a different hard-to-type character. Perl was only designed for the three data types, and adding more is a mess.
Perl 6 is a complete rewrite, but it keeps all the mess which has accumulated over the previous versions. This is not good. Sure, my const int $var = 27; may look neat (in the same way that, say, Pascal 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.
On a similar note is regexes. I'm an avid fan of regular expressions simply because a nondeterministic finite automata is far more flexible than linear code. However, Larry must have been smoking that cheap $2 crack when he wrote this. Does he want Perl 6 to be flex or something?
I won't be going on to use 6. It's a nice idea, but it's completely unnecessary. It won't make large projects any easier to manage (the language is still, at heart, an almighty hack -- an impressive one, but still a hack). It won't make OO any cleaner. It won't make development any faster. To put it bluntly, Perl scripts will still look less beautiful than our friend Mr Goat.cx. I'd prefer to use a language which has always been pure synthesis of science and engineering, not some half-baked imposter.
Perl 6 will be nice, but I'm guessing it will be the end of Perl. It can't do what it wants to do whilst still being based upon a nasty mess. There are now other options, which provide all of Perl's power and none of the mess. Sorry, but *BSD^H^H^H^H Perl is dying. Larry is buggering it up the ass without lubricants, just like Shoeboy is doing to Larry's daughter.
because c syntax is generally very strict. whereas perl is lax, and heavily context sensitive with lots of "magic" stuff like <> and $_ which have absolutely no meaning to a person who doesn't know perl.
and generally i agree. if you can't look at a line and no what it does without understanding the datatype, or what the interpreter will do then it's not a straightforward language. i.e., ugly.
