    # using MLDBM hash interface
    use MLDBM qw(DB_File JSON);    # use Storable for serializing
    my %db;
    my $dbm = tie %db, 'MLDBM' [ ... other MLDBM args ... ] or die $!

=head1 DESCRIPTION
MLDBM::Serializer::JSON provides an extension to MLDBM to enable storing the
additional columns as JSON instead of Data::Dumper or FreezeThaw.
JSON is very widely used - from Perl over Ruby to Python and surely
JavaScript and so on.
