YenForYang has asked for the wisdom of the Perl Monks concerning the following question:

I would like to keep persistent data inside a perl script, but this data might be updated every time it's run. This may sound like a strange thing to do, but is there any way I could alter the data after the __DATA__ token? It might be important to mention that the data doesn't need to be accessed after modification by the script process that did the modification--but it is accessed everytime before modification
