my $current_perl = get( $data, '/Languages/Perl/CurrentVersion' );
my @perl_urls = @{ get( $data, '/Languages/Perl/URLs' ) || [] };

DESCRIPTION
Data::PathSimple allows you to get and set values deep within a data structure using simple paths to navigate (think XPATH without the steroids).
Why do this when we already have direct access to the data structure? The motivation is that the path will come from a user using a command line tool.
