There is the Data::Dumper module (which is core module):

use Data::Dumper;

my $var = {'a' => 'Apfel', 'b' => 'Banane', 'c' => ['x', 'y', 'z']};

print Dumper($var);

Gives for the above example:

$VAR1 = {
          'c' => [
                   'x',
                   'y',
                   'z'
                 ],
          'a' => 'Apfel',
          'b' => 'Banane'
        };

which can be eval'ed back into Perl.
