Re: Using foreach to iterate through a hash in an array

[AnomalousMonk]

Sometimes it can be a great help just to see what you're dealing with. (Item 4 from Basic debugging checklist. Personally, I prefer Data::Dump::dd() and friends.) Ferinstance:

c:\@Work\Perl\monks>perl -wMstrict -MData::Dumper -le
"my %hash = qw(
   00:00:00 a  00:20:00 a  10:00:00 b  20:00:00 a  02:22:00 b
   );
 print Dumper \%hash;
 ;;
 my %hash2 = qw(
   00:00:00 a  00:20:00 a  10:00:00 b  20:00:00 a  02:22:00 b
   );
 print Dumper \%hash2;
 ;;
 my @bla = (%hash, %hash2);
 print Dumper \@bla;
"
$VAR1 = {
          '00:20:00' => 'a',
          '10:00:00' => 'b',
          '02:22:00' => 'b',
          '00:00:00' => 'a',
          '20:00:00' => 'a'
        };

$VAR1 = {
          '00:20:00' => 'a',
          '10:00:00' => 'b',
          '02:22:00' => 'b',
          '00:00:00' => 'a',
          '20:00:00' => 'a'
        };

$VAR1 = [
          '00:20:00',
          'a',
          '10:00:00',
          'b',
          '02:22:00',
          'b',
          '00:00:00',
          'a',
          '20:00:00',
          'a',
          '00:20:00',
          'a',
          '10:00:00',
          'b',
          '02:22:00',
          'b',
          '00:00:00',
          'a',
          '20:00:00',
          'a'
        ];
