I had problems with BSL at some point, I think, but it hardly matters, 
there's no point in doing it before BSL+, where it does work, except not 
with posns. Which I don't think I'll use with my students in the fall, 
but I can't guarantee that none of them will fall into that relatively 
minor pit. (If it were up to me, I would take the built-in definition of 
posns out. I don't think being able to use `make-posn' for a few minutes 
before introducing `define-struct' is worth the hassle.) --PR
