Thanks for your continued interest in Rcpp. It is always interesting to get
feedback from someone who has a fresh look at things.

You know the song: Your itch to scratch, your opportunity to patch. 

JJ has already explained to know how to circumvent the issue you created
yourself; I would add that you could also simply rename Rcpp::export to
something not matching the regexp; this is probably a sole call to search and
replace in any decent editor.

Well didn't JJ already tell you that he is not attempting to rewrite a C++
parser (or even processor) in a few hundred lines of R?
