Welcome to the Monastery, Dovkont. I hope your stay here will be a productive and educational one.

While your question sounds like a very interesting one, I will not try to answer it at the moment, because the answers I have seen posted look to be well on their way to pointing you in the right direction. I hope they provide the direction you need, and I (for one) would be interested in hearing how they help you solve the puzzle, or where they fell short, when you have had a chance to try them.

After reading the above, you may be wondering why I have bothered to post. You mention that you have a limited knowledge of perl, but sound like you have a need or desire to learn perl. That being the case, I feel you have come to the right place. The Monastery has a great deal of resources to offer to one wanting to learn (or learn more) about perl. The Tutorials section is an excellent place to start, and one that I highly recommend, containing information both on modules and techniques in perl, as well as information on the resources and general expectations in the Monastery (at the very least, the posts under the Welcome to the Monastery section may prove helpful in learning your way around here). Beyond the Tutorials section, there is the Categorized Q&A section, where a number of commonly-encountered questions are answered, the SoWP section where most questions are asked, and the Super Search, where you can try to determine if something you are wondering about has been asked about before. There is also the Chatterbox (or CB as it is known), where discussions occur most any time of the day, and questions can be asked,

I would caution you on thing or two, however.

1. First of all, as the improvement of the body monktorate is a major goal here, asking for help in a way that would not further that goal (such as having the response sent back to you via email) is a bit frowned upon. jeffa points out an alternate method for being notified in his tutorial. It's not that uncommon an occurrance, but something to be aware of.
2. Number two, the number of monks present at any time, and with a particular experience or skill set, varies by hour of the day and day of the week/month/year, so if you do not get a response immediately, don't fret too much about it.
3. Lastly, the experience range herein is enormous, as is the range of personalities and styles. If you receive a terse or somewhat "cutting" response from someone, try to learn from it, but don't take it too personally. Most of the monks herein behave as professionals, and I cannot recall a time when I have personally observed a response (except perhaps from someone new at the time) that was an intentional personal attack.

Again, welcome, and I hope your stay with be a productive, educational, and enjoyable one.
