Sorry I didn't know Data::Dumper, does it tell me more than simple print?

    Yes, and it’s a core module, so if you have Perl, you already have Data::Dumper:

    #! perl use strict; use warnings; use Data::Dumper; my %families = ( Flintstone => { husband => 'Fred', wife => 'Wilma', daughter => 'Pebbles', }, Rubble => { husband => 'Barney', wife => 'Betty', son => 'Bamm-Bamm', }, ); print Dumper(\%families), "\n";

    To get similar output with print alone, you would need to write your own loops.

    I didn't know Data::Dumper

    Seriously, get to know it as soon as possible, it’ll save you a lot of time. Or you might prefer one of the alternatives on CPAN, such as Data::Dump.

    Hope that helps,

    It tells you if the variable is blessed. (But so does plain ol' print)
