• Commented on Ricardo is pushing for smart match changes.
  I'm actually of the opinion that it would be quite positive for the Perl community. Right now, smartmatching, and given/when by extension, are surprising, confusing and way too complex. Which leads to nobody really using it. I can't use it...

• Posted About Obligations to Robert 'phaylon' Sedlacek

  First off, documentation is important. I love good documentation, and I try documenting my code as good as I can. But I do that because I want, I can, and I have the time. It is not because I have to.

  It's not that they don't want to have the view, they can't have it. You cannot "unknow" the internals. Saying they just don't want to see it is quite harsh. If they wouldn't care, they wouldn't put immense amounts of...
• Commented on Perl's Built-In OO
  Yes, change will happen, I agree. That's why I'm personally rooting for a small DWIMy implementation that can simply be ignored once it isn't enough anymore. Looking at CPAN and how long accessor generation has been done there, I don't...

• rjbs.manxome.org commented on Ricardo is pushing for smart match changes.

  The problem with making smartmatch behavior a pragma is, as Leon said, that pragmata generally work lexically, and this behavior is something we'd want to be changing based on the caller. Would swapping ~~ behaviors out with a dynamic pragma work? I don't know. I think it starts to make things difficult to follow.

  For some more on the difficulties with implementing ~~ behavior with pragmata, see this thread from p5p, in which Jesse L. began work on it and then ran into the problem described:

• Toby Inkster commented on Ricardo is pushing for smart match changes.

  I think the case for dynamic scoping is being overstated. If I write a module along the lines of:

  package Answers;
  use smartmatch 'core';
  use Sub::Exporter -setup => {
    exports => [qw( is_affirmative is_negative )],
  };
  sub is_affirmative {
    lc( $_[0] ) ~~ qw( yes si oui );
  }
  sub is_negative {
    lc( $_[0] ) ~~ qw( no non );
  }
  1;
  

  The fact that is_affirmative and is_negative use smart match internally are just implementation details. Somebody who imports the functions into their namespace won't necessarily know that, so it would be pretty odd if…

• Mark Stosberg commented on Ricardo is pushing for smart match changes.

  Richardo, thanks for the proposal, and Brian, thanks for highlighting an important issue for broader community input.

  Ricardo's proposal looked like a reasonable simplification to me.

  For some perspective, I was only able to recently get our production system upgraded from Perl 5.8 to Perl 5.14. We haven't even started to use smart matching in our code yet. I imagine a lot of people are in the same boat. There's no better time to get it right than now.

  With a positive outlook on growth, there will be more than double the users are smart match going forward than thei…

• transfixedbutnotdead.com commented on Ricardo is pushing for smart match changes.

  I'm not aware of Ruby having smart match? AFAIK Perl5 stole this directly from Perl6: http://perlcabal.org/syn/S03.html#Smart_matching

  You just prompted me to make my first ever post to p5p. I don't actively follow it (thanks, Mark Allen for the summaries!), but I will for a while in case my post draws any replies.
