在Perl中是否有内置的"hash to string"？

cpan install Data::Dumper

use Data::Dumper;

my %hash = (
    key1 => 'value1',
    key2 => 'value2',
    key3 => 'value3',
);

my $hash_str = Dumper(\%hash);

print $hash_str;

$VAR1 = {
          'key2' => 'value2',
          'key3' => 'value3',
          'key1' => 'value1'
        };
