• Commented on Perl 7, not quite getting better yet
  Smylers, another nugget to consider: Raku's "use DBI:from;" only work because Raku and Perl 5 have different library search paths (and methods, but that's secondary). If you plan to use the same search paths for mixed Perl 5 + 7...
• Commented on Perl 7, not quite getting better yet
  @Smylers that sounds like a really sensible approach, but there's some details to be worked out. If you run a script using perl7 foo.pl, and it "use"s a module, does it apply Perl 7 defaults to the module? It feels...
• Commented on Are Restricted/Locked Hashes A Failed Experiment?
  We use them a bit at work. They helped me catch some typos while refactoring very messy code. That said, I'd be fine with a replacement module that works similarly to Python's NamedTuple (that is, you specify the keys at...
• Commented on Using Role as Partial Classes
  To me, those roles sounds like a degenerate case of the normal "roles for code reuse" approach. Degenerate, because they are only composed into one class. But who knows, maybe in future there's something other than a character that does...

• Posted No Accepted Perl 6 Talks at YAPC::EU 2012? to moritz

  The YAPC::EU blog says "Our final voting round ends on Friday." So, Friday has gone by, does that mean that all talks that have not been accepted now have been rejected?

  And if so, are we really not going to have a single talk on Perl 6? I k…

• Commented on How (not) To Load a Module or Bad Interfaces Make Good People Do Bad Things

• Commented on Is 230 % 5 == 4? Sometimes it is.
  Output in Perl 6: 0. The reason is that 1.25 is represented as a rational number with integer numerator and denominator, so the identity 200 * 1.15 == 230 actually holds. Put another way: 15:47 <@pmichaud> I'd simply say that...
• Commented on Grepping exact values
  In Perl 6 this form works already, because each list item is simply smart-matched against the first argument (aka matcher). If the matcher is a block/closure, the smart-matching executes the block, handing the list item as a parameter. If it's...

  You can force coercion to a hash with return %( gather for %preds.kv ...) But I'm not sure if you like that bettter. Also a perfect Perl 6 implementation wouldn't need %!freqs{$item1}{$item2} //= 0; and similar lines. I'm pretty sure...

• Smylers commented on Perl 7, not quite getting better yet

  you run into weird issues where you have "use5 A::B" but "use7 A::C", and then A::B cannot upgrade to Perl 7, because all the callers still use "use5" to load it

  Not quite. use wouldn't mean ‘load and enforce v5 semantics regardless of what the file says’, but ‘load with v5 semantics by default’. A::B could still put a use v7 in there to switch itself to modern meanings. The point would be to avoid inadvertently loading a legacy module with modern semantics that it didn't know about, but nothing stops it opting i…

• Leon Timmermans commented on Perl 7, not quite getting better yet

  No apologies needed, but taking things to p5p may be a good idea indeed.

• tnish commented on Perl 7, not quite getting better yet

  Can we just have a /usr/bin/perl-ng (for 'next gen', or any other cheesy suffix we can think of)? It doesn't take over /usr/bin/perl, we won't end up with multiple perl8, perl9, etc... And it still has "perl" in it. /usr/bin/perl-ng will be 7 and beyond, /usr/bin/perl will be 5.x. Distros can ship a perl 7+, and a perl 5.x. It will be annoying to remember adding -ng to perldoc, cpan, and a few others, but, seems like something we can get used to (I'd just use shell aliases or something).

• George Magklaras commented on Perl 7, not quite getting better yet

  Nice article, I see most of your points. For the purposes of accuracy, however, you might like to correct what you say about Python3 and the Linux distros. Fedora (since Fedora 32 which is the latest stable) has switched to Python3 by default (and yes, this has upset many dev folk that were still relying on Python2). Gentoo (I think) has a compilable option to switch to Python3 and OpenMandriva has also ditched Python2. So, things are happening there.

• brian d foy commented on Let's add Git userdiff defaults for Perl and Perl 6

  This is over a decade later, but git now has this in core with many more patterns. See userdiff.c (which you already linked to). You still have to associate the file endings with a the perl driver as you show.

  There's a big caveat: the pattern only matches against lines that aren't shown in the hunk. For example, if you change the first line after sub foo, the sub foo { line shows up as part of the hunk context and is not searched for the pattern. This threw me for a bit, but I guess it makes sense when. you can see the subroutine in the …
