At this point, and at that level of dicussion: If I was you, I would hire somebody (or ask for a volunteer) that does the code review with me and reads manual pages for me, so I can learn something - I guess, maybe I wouldn't either.
At least I would make the whole blob available somewhere, maybe some kind soul wants to sort that out. But I could be uneasy about it, and again, wouldn't do that, either.
So, sorry for now. If I have spare time, I might re-read that thread and annotate tersely what parts of the perl documentation and which RFCs need to be read. But that could take some ten years. Maybe it's done earlier, or not at all.
