Greetings,

I have a default array of hashes. I replace the defaults, if they exist, with an arrayref. Is there a more efficient way to do this?

#!/usr/bin/perl

use strict;
use warnings;
use Data::Dumper;

# Defaults
my @t = (
   {
      'label' => 'kept',
      'value' => '0',
   },
   {
      'label' => 'notkept',
      'value' => '0',
   },
   {
      'label' => 'repaired',
      'value' => '0',
   },
);

# Get this from another sub
my $a = [
   [ 'kept', '1', ],
   [ 'repaired', '3' ]
];

# Overwrite defaults with arrayref
for my $i ( @{ $a } )
{
   for my $t ( @t )
   {
      if ( $i->[0] eq $t->{label} )
      {
         $t->{value} = $i->[1];
      }
   }
}

warn Dumper( \$a );
warn Dumper( \@t );

Produces:

$VAR1 = \[
            [
              'kept',
              '1'
            ],
            [
              'repaired',
              '3'
            ]
          ];
$VAR1 = [
          {
            'value' => '1',
            'label' => 'kept'
          },
          {
            'value' => '0',
            'label' => 'notkept'
          },
          {
            'label' => 'repaired',
            'value' => '3'
          }
        ];
