Answer: How do I make an array of hashes?
contributed by chromatic

my @array = ( { 'name' => 'Chuck', 'job' => 'roustabout', }, { 'name' => 'CowboyNeal', 'job' => 'code monkey', }, );
You can also use normal array operations (such as push) to modify an array:
push @array, { 'name' => 'vroom', 'job' => 'stacking blocks' }; print $array[0]->{name};
See perlman:perldsc for more information.

If the hash has already been created, you can store references to the hash in arrays:

push(@array, \%some_hash);

and then when you pop them off:

$hash_ref = pop(@array);

you'll get a scalar back which can be dereferenced to get at the values of the hash:

$value = $hash_ref->{'key'};
