  Just as addon, the B in KBOS is meant literally. What I show here is merely the base level. There is also a logging, event and UI comand system involved. So I naturally never thought about so far, that other...
• Commented on Introducing KBOS
  well, KBOS classes are not ment to be inherited from. If you define a class Bumblebee, there will be later no package Bumblebee, let alone subs in it, so parent would run empty. All information which methods and attributes the...

  i see your issue, but luckily I don't have even think about and hut my precious brain, because KBOS has no inheritance (for reasons like you present here and as written in the post). But to fully adress you question,...
• Posted Introducing KBOS to lichtkind

  Starting even before Moose, we (in the Perl 5 world) have a plethora of Modules extending the syntax of the language with Perl 6 and more in mind. The following article sums up not only my 2 and a half cents on the subject but also an attempt to implement it. It should be of interest to anybody…

• Posted Perl6::Math::Matrix (Part 5: patient with docs) to lichtkind

  If you write any software package, you have to document it. This simple truth drives more than few developers into despair. But there is also a way to craft good documentation and make the writing of it a useful part of the development. This is the closing part about authoring a Perl 6 module and…

• Posted Perl6::Math::Matrix (Part 4: naming methods) to lichtkind

  While reflecting on how to write a good Perl 6 module, I thought a lot about how to properly name my methods. In this text I want to summarize what served me, which is a direct continuation of the

• Graham Knop commented on Plan for perldoc 4.0

  Sites like MetaCPAN are probably the primary places to show images in pod documents, so MetaCPAN is probably the best place to discuss images in pod. I wrote the current implementation of the's image handling, and I'd be interested in hearing concerns or suggestions. Either drop by the IRC channel (irc.perl.org #metacpan) or file an issue.

• KES commented on Don't use until, unless...

  I will agree with you that unnecessary negation is bad. But I will not agree that `unless` keyword usage is complex.

  You should just use it in right place. By `unless` you should mark code which SHOULD NOT RUN in usual case.

  Look:

  sub process {
  my( $self ) = @_;

  return unless $self->is_valid; # Read this code as: $self should be valid

  my $result = ...;

  return $result;
  }

  Look next examples where I use `unless` with success (And I think code with `unless` here is clear in compare to usual `if`):

  $s…

• Randal L. Schwartz commented on Don't use until, unless...

  Just really avoid "unless... else". That's... just.... wrong.

• Toby Inkster commented on Introducing KBOS

  Hmm, but what if Base were written using KBOS, and Derived was just a plain old Perl package with use parent "Base";? Even if you're not implementing facilities for inheritance, it's hard to ignore that inheritance does exist in Perl.

• Toby Inkster commented on Announcing Zydeco

  There's a benchmark script included in the examples directory within the distribution. It compares Zydeco against Moops, MooseX::Declare, and Dios, which all offer a similar declarative syntax for object oriented Perl. This is of course a runtime comparison rather than compile time.

  I haven't done any formal benchmarking on comp…
