Super! Also, best definition of bottom I've yet seen -- "ignoring _| _, which is a party pooper". Like good code, it's short, to the point, and obviously correct.
This brings up something I've thought about: On page 8, it is said that Pointed doesn't need to be checked because the theorem comes for free, but the free theorems paper was based upon total functions only; does having _|_ affect the free theorem for Pointed?
This was my question to Janis Voigtländer after his HaL 3 talk. He said that the free theorem stuff also holds in the presence of _|_, it’s just a bit more complicated to prove it. At least, this is how I understood it. :-)
This paper was recently cited in -cafe; doesn't it help here? http://citeseerx.ist.psu.edu/viewdoc/summary?doi=10.1.1.59.8232 -- Roman I. Cheplyaka :: http://ro-che.info/ "Don't let school get in the way of your education." - Mark Twain
