• Commented on Are Restricted/Locked Hashes A Failed Experiment?
  I've used restricted hashes in a few ecommerce situations where they were indispensable, exactly as important and useful as `use strict` for making sure lexical accesses aren't typos. I don't have any opinion about whether restricted hashes should be part...

  kid51: short example

  % perl -le '
  use Getopt::Long;
  use Hash::Util qw(lock_keys);
  lock_keys %Opt, qw(mrg);
  GetOptions(\%Opt, "mrg=i") or die;
  if ($Opt{mgr}){
  print "INT=$Opt{mrg}";
  }

  Attempt to access disallowed key 'mgr' in a restricted hash at -e line 6.

  Locked hashes are great, but if the implementation is slowing down all hashes, then I agree they should no longer be built in, and should be moved to a module

  That said, I think it's an important enough feature that this module should be bundled with Perl, so that people relying on fields.pm (which was first released with Perl 5.5) and Hash::Util (Perl 5.8) won't need to install anything extra.

  I have used Hash::Utils more than once, specially in OOP projects that I was using "default" OOP model of Perl (not Moose or anything like that).
  On the other hand, I usually don't start using it from scratch, usually when things starts to getting more complex and bugs starts to appear it is a sign that I should consider using it.
  It is good to be have options... sometimes you need flexibility (like expanding a…
