• Commented on When Laziness Isn't
  But I'm not clear why plain $ARGV[0] doesn't work there. Your suggested '$$ARGV[0]' doesn't mean the same thing as '@ARGV[0]' in perl directly. Is this a shell thing? (I'm using zsh.)...
• Commented on When Laziness Isn't
  @briandfoy - My shell now sources a separate zsh_aliases file with many dozen aliases - about half of which I've learned from you, like your set of very handy number conversions. I'm sure others collect yours, too. So it seemed...
• Commented on A deep dive into the Perl type systems
  Thanks, Leon. You've done a great service with this - for Perl practitioners as well as skeptics and newcomers. I found one sentence I had to read a few times before understanding, under the "Assignment" heading: "Any scalar can be...

  Hey Saif, Great to know you're in the calendar coders club. I love the non-orthogonal challenges of programming around dates and calendaring. There's only one word for it!...
• Commented on My 2023 in Perl
  Really grateful for your work on Crypt::Passphrase!...
• Commented on My new modules in 2021
  @Leon, Thank you for Crypt::Passphrase! I tried it as soon as I read about it. It's now in use in several production apps I work on, providing a higher comfort level for the future as the encryption carousel keeps spinning......

  Hats off to the P6 devs for enabling this high degree of optimization!...
• Commented on 6lang: The Naming Discussion Update
  What I've noticed: Other than people caught up in the name debate, and people trying to be respectful of those caught up in the debate, lots of writing about the language resorts to the practical abbreviation "P6". This is in...

• Commented on Looking at DBI Part 17, Wasn't that a Police Album
  Thanks for this series. Looks like a typo here: We can then check the statement handle with the 'pg_ready' method which returns 'true' if the query is finished, some thing like this while (!$dbh->pg_ready) { ... Shouldn't that have been...

  Show Perl 6 code to a non-Perl programmer and let him/her decide. He/She will definitely answer "it's Perl".

• JJ Merelo commented on 6lang: The Naming Discussion Update

  Could be x-lang (eks-lang). Not so bad, not taken as far as I know.

  It really has been fascinating learning for me. To think that astronomers detected a difference in consecutive years of less that 0.1% centuries ago, and compensate for it is amazing. The maths is the clever bit. I am planning to cut out dependencies like DateTime that do all the work of calculating dates, just so that I can explore how this is actually done.

• Leon Timmermans commented on A deep dive into the Perl type systems

  That's just an editorial mistake on my end, I've updated it to hopefully be more clear.

  And very amusing: I still use a module based on blessing the whole glob/symbol table. It's a very powerful tool for me - typically the hash handles transient data like successive records from an iterator, the array is a buffer for capturing things for use later, the IO is for quick output o…

  The $$ in $$ARGV[0] is being replaced when the alias is created:
  tony@venus:~$ alias u="perl -le 'system q(uuidgen) for 1..$$ARGV[0]'"
  tony@venus:~$ alias
  alias u='perl -le '\''system q(uuidgen) for 1..95370ARGV[0]'\'''
  The shell doesn't use @ here so @ARGV[0] works.

  The single $ARGV is replaced with nothing, so it also doesn't work:
  

  $ alias u="perl -le 'system q(uuidgen) for 1..$ARGV[0]'"
  
  tony@venus:~$ alias
  
  alias u='perl -le '\''system q(uuidgen) for 1..[0]'\'''

  You can avoid the replacement with bash an…
