use MLDBM qw(DB_File Storable);
use Fcntl qw(O_RDWR O_CREAT);
tie(%hash, "MLDBM", "file.db", O_RDWR|O_CREAT) || die("tie: $!");
Unfortunately, you have to change how you assign to the hash, from:
$hash{$key1}{$key2}{$key3} = "foo";
to
my $tmp = $hash{$key1};
$$tmp{$key2}{$key3} = "foo";
$hash{$key1} = $tmp;
Accesses don't need to change, though.
