I suggest we also add: 4/ Choice of primitives After living with DAML+OIL for almost a year now, and having talked to lots of people who have used it (and even more people who haven't), I am getting pretty convinced that we got the 80/20 balance wrong in DAML+OIL: 20% of the primitives account for 80% of the usage/required expressive power, and the other primitives contribute to a pretty high step-in cost. I would suggest we reduce the language to deal with these issues. Also, we have lost rather too much of the "frame-style" modelling in the language. Too often DAML+OIL requires a significant mental shift before one can express the intended knowledge. I don't think either of these points will require a whole-sale redesign. I am willing to contribute to both of these issues. Frank. ----
