Hello,

I'm trying to use the Perl MongoDb module to extract a list from mongo, alter the data and replace the original list. The replace operation has gone wrong. I have tried this code: 

$col->update(
          { "host" => $host },
          {
                     '$set' => { "timestamp" =>  [ @new ] }
          },
          { 'multiple' => 1, 'safe' => 1 }
) || die "$!";

[download]

This does not seem to work as the list is emptied by the update. What have I done wrong?
