Re: accessing elements in array of hashes

The core Data::Dumper module is an extremely useful tool when trying to work out whether your data structures have turned out as you intended.

$ perl -Mstrict -Mwarnings -MData::Dumper -E '
my %h1 = ( a => 1, b => 2 );
my %h2 = ( z => 26, y => 25 );
my @badAoH;
push @badAoH, %h1;
push @badAoH, %h2;
print Data::Dumper->Dumpxs( [ \ @badAoH ], [ qw{ *badAoH } ] );
my @goodAoH;
push @goodAoH, \ %h1;
push @goodAoH, \ %h2;
print Data::Dumper->Dumpxs( [ \ @goodAoH ], [ qw{ *goodAoH } ] );'
@badAoH = (
            'a',
            1,
            'b',
            2,
            'y',
            25,
            'z',
            26
          );
@goodAoH = (
             {
               'a' => 1,
               'b' => 2
             },
             {
               'y' => 25,
               'z' => 26
             }
           );
$

I hope this is helpful.
