• Commented on A (not so) simple matter of privacy
  I previously proposed allowing the syntax $object->&method_name to call a lexical sub (my sub method_name). This fits more with traditional perl OO, but it should be possible to extend to Cor methods. https://github.com/Perl/perl5/issues/18621...

  Yes, tables are allowed. You can see what HTML is allowed in the MetaCPAN code. MetaCPAN also provides a Pod renderer you can test with....
• Commented on Speedup Travis by tweaking your Dist::Zilla config
  I despise working with any Dist::Zilla setup that modifies the working directory during a normal build. Doing automatic commits is even worse. If have files you want to regenerate easily, I think the [Regenerate] and [Regenerate::AfterRelease] plugins are much more...
• 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...

  I'd be interested in seeing your benchmark script to see what you are actually comparing, as some of the numbers seem a bit odd. Also note that MooX::TypeTiny exists and should make the combination of Moo and Type::Tiny as fast...

• Commented on Missing Smart Match
  I don't find $x in @a very comprehensible because it isn't obvious how it will be comparing elements. Will it use string equality or numeric equality? What if you need to pick one or the other?...
• Commented on Missing Smart Match
  Trying to use looks_like_number to "fix" my example means that "01" ~~ "1" would return true. That is currently not the case. There are other similar cases that are more subtle. It just can't be done properly with perl's untyped...

  Here's an example of a failure using the type of check you showed.my $scalar = "1welp"; my @array = (1, "foo"); print "smartmatch is broken\n" if ($scalar ~~ @array);I don't think anyone's happy that smart match couldn't be fixed properly,...
• Commented on Travis-CI and latest version of Perl 5
  Adding a 'latest stable' target to travis-perl helpers isn't something that had occurred to me, but if you think it would be worthwhile, I could definitely do so. And I would certainly welcome any other feedback on it too....
• Posted Moo 2.0 to Graham Knop

  The next stable release of Moo will be version 2.0, and will include some modules, and may help point out flaws in the existing code.

• Commented on Kiss Kiss Shebang Shebang
  local::lib no longer loads File::Spec. The footnote mentions this, but is also incorrect. File::Spec isn't used on Windows or Mac OS X. It's only used on VMS and Mac OS Classic, where it seems unlikely the rest of local::lib will...
• Posted Travis-CI Helpers for Perl to Graham Knop

  I deal with a lot of modules that promise backwards compatibility with older versions that old when developing, accidentally introducing incompatibilities is always a risk. Having a continuous integration system check…

• Commented on perlbrew on OSX
  The problem is that you are installing modules into a local::lib, but that directory isn't part of the library search path. PERL_CPANM_OPT=--local-lib ~/perl5 means that things are always installed into ~/perl5, but the corresponding PERL5LIB isn't set up to load...

• Commented on Conflict Resolution: local::lib and git's Perl
  I have a pending addition to local::lib that will install perl modules in a version specific directory. perl will then automatically pick those directories up, even they won't be listed directly in PERL5LIB. This will mostly fix problems of this...
• Commented on Moose, Mouse, Moo what next 'M'
  There's no reason OO is less appropriate for CGI or command line programs, especially if they share components with a larger system. The only real concern is if the overhead is worth it. And for Moo and Mouse, you won't...
• Commented on Extracting values from a list of (key, value) pairs
  There is a small mistake in your code. @N has an odd number of elements. pairkeys will warn about this if warnings are on. Another option for this is doing an array slice: @N[ map $_*2, 0..(@N/2)-1 ] It's slower...

  Why do you say that? Not that structured exceptions are a bad idea, but why are they any more important for signatures than any other part of the language?...

• Commented on Array and hash intersections with map, grep, and state

• Commented on CPAN modules for converting markdown to HTML
  While Moose certainly has a significant startup and memory cost, it should have little to no impact on normal runtime operations. For WWW::Curl::Simple from the HTTP benchmarks, the slowness is not inherent to Moose itself but in how it is...
• Commented on Devel::Confess - Include stack traces with all errors/warnings
  I did propose it to the author of Carp::Always, but he didn't want to add it. He prefers keeping Carp::Always simple and small, a decision I can't fault him for. My module has more than 6 times as much code,...
• Posted Devel::Confess - Include stack traces with all errors/warnings to Graham Knop

  Edit: Since writing this, I've decided on a proper name. Devel::Confess is the name for this module going forward. Carp::Always::EvenObjects exists now only as a wrapper around Devel::Confess.

  Carp::Always is a very useful mod…

• Commented on The grep test - my personal experience
  Even when you "know the codebase", there will come times where you want to find all invocants of a function/method. Especially when refactoring. Like so many other things, keeping thing grep-able isn't a hard and fast rule. But dynamically generating...

• Aristotle commented on A (not so) simple matter of privacy

  # which fields are visible from this eval?

  Isn’t the answer simply “none”? It seems a trick question. Fields aren’t visible inside a sub, whether it’s lexical or not, no?

• Salvador Fandiño commented on A (not so) simple matter of privacy

  Isn’t the answer simply “none”?
  

  Yes, that was the conclusion: it is not a good idea to let lexical subroutines, declared at the class top level, access the object fields.

  It seems a trick question. Fields aren’t visible inside a sub, whether it’s lexical or not, no?

  Well, IMO, they should be visible if the sub is declared inside a method. For instance, I would expect the following code to work:

  use Scalar::Util qw(first);
  
  class A {
  
    field $…
  

• Aristotle commented on A (not so) simple matter of privacy

  I would expect the following code to work:

  Well, yes, obviously, a closure is a different kind of situation. The question would be what happens in a named sub declared inside a method – where I would expect the exact same behaviour that the “variable will not stay shared” warning cautions against currently. And I would expect the use of a lexical sub to cure the problem, the same way it currently does for regular subs.

• Brett Estrade commented on Looking for a new owner for my modules

  How do I request to be come a member of https://github.com/PerlRedis? I like redis, though I don't use it as often as I probably should. I'd be happy to help tackle prioritized bugs as time permits. My GH is oodler577 and email is oodler@cpan.org.
