OK, so I have contributed XML::Twig and I wished there had been an answer "I have contributed a module to CPAN but I'rather not have people look too closely at the code" ;--(

I have found that actually few people look at the code, although it's probably because few people use the module at all. I had mostly comments (and even patches) on the documentation. The fact that the module is pre-processed and that the actual code is not in XML::Twig.pm probably does not help either.
