I'm not actually sure what this section was supposed to be doing - and what syntax it was accomodating.  I was able to pass all of my own syntax tests as well as the rubinius mspec with this section commented out, but it seems like it had to have been there for some reason.  I couldn't find a commit message for it in this repository or in the repository that this repository is migrated from.

So, what is it supposed to do?
