    I really enjoy both Perl and Ruby (Ruby even more so because everything's an object and the syntax for iterators/blocks/closures).

    Would be interesting to see if parrot successfully unites various scripting languages.

      Everything in Python is also an object, it has a clean and terse syntax and the language and it's libraries is already a reality. I've been using it to do some SERIOUS work at a telecomunications company. It's not a toy language.
      • I would agree. Georgia Institute of Technology (Georgia Tech) has now changed the undergrad/cs/engineering curriculum and has made Python the FIRST language that students learn. GT is especially known for the engineering program and python is being used a lot by scientists and engineers around campus.
        • wow that is awesome...I had no idea...I would like to clarify that the mission of CS courses at GT is to "teach concepts," not to "learn languages". Hence my first CS course (august of 1999...still have another year of my undergrad...I am lazy) being taught using only pseudo code. I learned the concepts, sure, but the class would have been a lot more fun had we been using Python.

          At my job I work about half in C++ and half in Python...and it is a joy to use. I used to hate it and would only code in Perl.

            And everything being an object is not necessarily a good thing either - a lot more overhead is involved when you have to create an entire object to do some simple communications.

            Surely too many, not enough and just right are subjective judgements. There is no need to use any parentheses in OO, either in practicality and certainly not in thought process, it is an imposition of the language which may make it easier to understand, to some degree, by some. The contents of parentheses are just elements of a command: a vectored command (embedded or not); doing away with parentheses, and the linear thought process of procedural programming it all arises from, could allow proper n-dimens

          That's a bit unfair; Ruby's libraries tend to be of high quality, and they cover a fairly respectable amount of ground even if they are a little more limited in numbers. Two or three excellent implementations is better than two or three reasonable ones and a thousand crappy ones.

          It's been shown to be slower than some other languages; however speed hasn't been an issue with me yet

          Slower how? Certainly development time wise Ruby is one of the fastest languages on the planet; when it comes to runtime performance it's about on par with PHP. Finding hotspots isn't difficult with the various profiling, benchmarking and testing modules about, and you'll struggle to find a language where writing a C extension to optimize out a hotspot is so easy.

          Scope is broken in some cases; this is the biggest problem with Ruby and Matz admits it

      I was at the OsCon '04 Keynotes. Larry Wall's State of The Onion Address was entertaining, if not a bit hard to follow at times. When he was discussing ADHD it seemed as though he was mostly using it to contrast his "opposite" problem, and make the point that any kind of singular personality (strictly ADHD bounciness, or strictly task-switching deficiency) was a bad thing, or at least not as productive as a good balance.

      In his talk about Tom Christiansen his tone seemed to be half humour/half endearing. I'd say there's no ill will between them, or between Larry Wall and people who have ADHD in general.

      If you run xscreensaver -demo and follow along you might get a bit clearer picture of what he wanted, but then again maybe not. Half the time it seemed like he was running the wrong screen saver, or the screen saver he chose didn't appear to apply to his topic. Then again, at other times (like where he demonstrates how his mind solves puzzles) it was very funny and appropriate.

      OT: What I really want to see is the "Life, the Universe, and Everything" keynote transcription, it was the last one that night. In it I saw perl6 extensions used to create variables with dual values, and Conway's Game of Life written in perl...in Klingon! If anyone has a link to this program, or can remember the CPAN::Klingon module's name it'd be great.

      It was great being at the State of the Onion address in person, but from reading last year's address, I came away with the opinion that Larry Wall is a better author than orator, and his language can be mildly stilted at times. But what more could be expected from a hacker?

    I was recently having a discussion about Perl, and it briefly touched upon Perl 6 and its targetting the Parrot virtual machine. I would like to know what slashdotters think about the issue.

    So, just to hear your opinion: do you think Perl is going to be better off for having a virtual machine? I personally think it's much easier to get good performance from
    higher-level languages than machine code (which is possibly why Parrot code seems to be more high level than typical machine code). Of course, going further away from
    the source language (thus lower level) increases chances of interoperability with other languages, which is something that Microsoft has realized with .NET. I am really

    For instance there is now OO COBOL but the only people that use it are COBOL programmers who are stuck, perhaps because of their company's dictates, perhaps by choice, with COBOL. In the same way perl may be heading towards irrelevance wrt "mainstream" language. I've written commercial perl in the past, it was a pain then and it's still a pain now. The thing is that now there are alternative languages in the same space (python, ruby etc., php for web side) that do the "perl thing" better than perl.

    Perl was great, it introduced many people to programming, just like COBOL did. But now it's time to move on. To move on to languages that learnt from perl, that improved on it, that don't have to drag around a syntax and culture that values neat tricks and trying to guess what the programmer really meant over providing the needed building blocks and letting you build code that does what you say, not what it thinks it heard you say. Or even, dare I say it, to move on to languages outside the perl family for some programming and choose the right tool for the job for a change.

          I think it's a false dilemma that you can either use Perl flexibly or write maintainable code. Surely a flexible language allows you to choose a coding approach that fits your team!

          Regardless, I fail to see how agreeing on minutiae such as brace placement and indentation will make Perl inflexible. I don't understand on how agreeing to write short subroutines, use a consistent and descriptive naming scheme, and build a comprehensive test suite is unperlish.

          In short, I think if your team can agree on a coding style, you can solve the maintainability program.

          If you can't agree on a coding style, it doesn't matter which language you choose.
