--- Comment #15 from Vincent Povirk madewokherd@gmail.com 2013-04-05 10:56:59 CDT --- Yes. I'm working on it (slowly).
I have something that seems to work, and I think what remains is to add test cases and go back and implement it cleanly, and get it accepted into Mono. I can post what I have as a diff if anyone is interested.
