  • Commented on Perl 6 Colonpairoscopy
    I consider colonpairs in method arguments THE BEST feature of Perl 6, hands down. It makes large codebase very consistent because it promotes genuine laziness when choosing variable names. Consider common P5ism like: my $name = 'John'; ... sub authenticate...
  • Commented on 6lang: The Naming Discussion Update
    Slang is a term for describing informal language used in some environment because it is NOT easily understandable by common people. And because of prison slang this term still means 'the vocabulary of "low or disreputable" people' (Wikipedia quote). That's...
  • Commented on Writing Declarative Perl
    Personally I find declarative programming very obfuscated for two reasons: Call to attempt() is outside Steps(). That is the very core of declarative programming - to separate process definition from its execution. But this leads to: Unclear SUCCESS/FAILURE triggering. "If...

  • Posted Running mixed Perl 5 and Perl 6 tests. to Pawel bbkr Pabian

    Those two tricks are especially useful when refactoring big codebase from Perl 5 to Perl 6. Such process may take weeks or even a months, and you will encounter two cases:
    1. Some features are still in Perl 5, some are fully refactored to Perl 6. So you want to

  • Dirk Deimeke commented on Swiss Perl Workshop - Post Event & Future

    In my opinion the (Swiss) Perl Workshop is about meeting people sharing the same mindset and sometimes very special sense of humour.

    Having interesting talks and workshops is a perfect bonus.

    So, it could be an option to search for a conference and ask the organizers for having a Perl/Raku Track.

    This is how it works with dev rooms at FOSDEM.

  • domm commented on Swiss Perl Workshop - Post Event & Future

    One benefit of local / small events compared to big events is that they can and should be in the local language.

    I know that this is a bit more complex in e.g. Switzerland than in e.g. Austria, but it is so much easier for especially new speakers to speak in their native language.

  • laurent_r commented on Perl Subroutine Signatures Opinion Blog

    Hi Yuki, I agree with you. When I started to use Perl, that must be 17 or 18 years ago, I found that using @_ or @ARGV was just fine.

    And when subroutine signatures were introduced, I really didn't care that much about them. But having used Perl 6 (now known as Raku) for quite a few years by now, I realized how useful subroutine signatures can be. Sometimes, a subroutine will not even need to have a body, as the signature will do everything that you need. Now, of course, Raku (or P6) is much more type-oriented than P5, so that useful signatures are more difficult to implement in P5. …

    Because I'm lazy.

    OK!

    If I and you are lazy, we don't want to learn a lot of syntax.

    It would be nice to add a grammar that is just the right size for convenience and less learning.

    And

    Perl have a history and Perl users on Unix/Linux and Text Processing have long convention.

    I hope well balanced choice instead of all possible features.


  • Yuki Kimoto commented on Perl Subroutine Signatures Opinion Blog

    Raku have a lot of built-in types and type checking. This is Raku design.

    These effect PHP, Python, TypeScript.

    On the other hand, there are long time Perl users(which contain me) expect and feel attractive that Perl is pure dynamic language in core features.
