Perl - Array of Objects - perl

Question

Noob question here.
I'm sure the answer will be create objects, and store them in an array, but I want to see if there is an easier way.
In JSON notation I can create an array of objects like so:
[
{ width : 100, height : 50 },
{ width : 90, height : 30 },
{ width : 30, height : 10 }
]
Nice and simple. No arguing that.
I know Perl is not JS, but is there an easier way to duplicate an array of objects, then to create a new "class", new the objects, and push them in an array?
I guess what would make this possible is an object literal type notation that JS provides.
Or, is there another way to store two values, like above? I guess I could just have two arrays, each with scalar values, but that seems ugly...but much easier than creating a separate class, and all that crap. If I were writing Java or something, then no problem, but I don't want to be bothered with all that when I'm just writing a small script.

Answer 1

Here's a start. Each element of the #list array is a reference to a hash with keys "width" and "height".
#!/usr/bin/perl
use strict;
use warnings;
my #list = (
{ width => 100, height => 50 },
{ width => 90, height => 30 },
{ width => 30, height => 10 }
);
foreach my $elem (#list) {
print "width=$elem->{width}, height=$elem->{height}\n";
}

Answer 2

an Array of hashes would do it, something like this
my #file_attachments = (
{file => 'test1.zip', price => '10.00', desc => 'the 1st test'},
{file => 'test2.zip', price => '12.00', desc => 'the 2nd test'},
{file => 'test3.zip', price => '13.00', desc => 'the 3rd test'},
{file => 'test4.zip', price => '14.00', desc => 'the 4th test'}
);
then access it like this
$file_attachments[0]{'file'}

Pretty much the same way you do it in JSON, in fact, use the JSON and Data::Dumper modules to produce output from your JSON that you could use in your Perl code:
use strict;
use warnings;
use JSON;
use Data::Dumper;
# correct key to "key"
my $json = <<'EOJSON';
[
{ "width" : 100, "height" : 50 },
{ "width" : 90, "height" : 30 },
{ "width" : 30, "height" : 10 }
]
EOJSON
my $data = decode_json($json);
print Data::Dumper->Dump([$data], ['*data']);
which outputs
#data = (
{
'width' => 100,
'height' => 50
},
{
'width' => 90,
'height' => 30
},
{
'width' => 30,
'height' => 10
}
);
and all that is missing is the my
