How has support for multidimensional data structures changed across recent Perl versions?

Support for multidimensional data structures in Perl has evolved, especially with newer versions enhancing syntax and functionality that allow for more intuitive handling of complex data types. Starting from simple arrays and hashes to more intricate structures that can incorporate arrays of hashes or hashes of arrays, Perl has maintained its flexibility in dealing with multidimensional data.

Perl 5 introduced advanced data structures like arrays of arrays or hashes of hashes, and since then, newer versions have improved documentation and examples, making it easier for developers to utilize these structures effectively.

        # Example of a multidimensional array in Perl
        my @array_of_hashes = (
            { name => 'Alice', age => 30 },
            { name => 'Bob', age => 25 },
            { name => 'Charlie', age => 35 }
        );

        foreach my $person (@array_of_hashes) {
            print "Name: " . $person->{name} . ", Age: " . $person->{age} . "\n";
        }
