Regarding: "The next thing that bothers me is in your $wanted->() sub. You're not checking for the validity of your pattern match, and then you're subsequently relying on $2 to contain a reasonable value. Don't rely on captures unless you're certain that there was a match. Just don't; you will get into trouble eventually with that approach."

How would you go about ensuring the match? Would you just do a if to test if there is something there, or would there be a remenant from the last match? If there was a remenant would you need to assign it to a global and then first test if it is the same as the global?

Any suggestions would be greatly welcomed.
