What's interesting is that the author touches on explicit attribute declarations in slide 37 - something which I think John Nagle suggested recently, although apologies to John and the person in question if it was someone else. Without actually declaring types for those attributes, it's possible to make some potential efficiency gains, and I think that interfaces (really clusters of attributes in this case) can be deduced with only this information explicitly stated by the programmer. Of course, you can also try whole program analysis to get an idea of which instances have which attributes, too. Certainly, there are lots of approaches available without writing type names all over the place, as seems to be the fashion in certain circles.
