I have a data structure returned by Frontier::Client that "print Dumper($result)" shows as:

$VAR1 = [
          {
            'state' => 'CA',
            'suffix' => '',
            'lat' => '37.783941',
            'city' => 'San Francisco',
            'number' => '833',
            'zip' => '94103',
            'long' => '-122.404900',
            'prefix' => '',
            'type' => 'St',
            'street' => 'Mission'
          }
        ];

print $result->{'city'} gives error Argument "San Francisco" isn't numeric in hash element. which I don't understand. How do I get at this data? All I can do right now is list the keys:

foreach my $key ( sort keys %{$result} ) {
   print "$key\n";
   }
