Data::Dumper does too much work, making Perl code on the way out, and
then having to eval it on the way in.

My favorite is Storable, now part of the Perl core, but easily found
in the CPAN for older Perls.

Also look into Tie::MLDBM, which gives an indexed way to partition a
file, using Storable automatically to store and retrieve complex

If you want something more interesting, look at Tangram, which
provides an object to relational-database mapping.
