Comment(by carter):

 Interesting paper! (and the examples therein are nice!)

 on the associated project page
 http://www.cis.upenn.edu/~eir/packages/nokinds/

 it says " ... seem to have accepted the inevitability that these ideas
 will some day be merged. "

 Is that a quirk of turn of phrase, or is there some downside to this
 direction that isn't in the paper/documentation I see? (I'd assume the
 former, but doesn't hurt to ask explicitly)
