Have each module define text lines that become part of a big Parse::RecDescent grammar you evaluate at the end to generate the top rule. As long as your basic lexing rules are consistent you should be OK. This gives you the most flexibility, as long as you control all the modules and the load order. I also think it's the most readable approach and it only exposes the functionality you want to expose.
