Comment (by goldfire):

 Bad news and good news.

 Bad news first: my student who said she was keen on this has changed
 direction and will not be working on this in the near future. Good news:
 she's spending the semester learning more type theory, and I'm hoping to
 get her to tackle something like implication constraints or visible type
 application in patterns or something more type-y. Even better news: where
 there was originally one student, there are now three. So the future bodes
 well.

 In any case, I have no intention of myself or anyone in my immediate
 vicinity to work on this ticket.
