Yes: I haven't made up my mind in either way.  Although (b) might seem
most efficient, a logical set of symbols to put into the list doesn't
pop into my mind (but hey, it's getting late :-).

The problem with (c) in this case, is that the function would
duplicate a lot of logic from the collision code, and would be fairly
hairy to write in Scheme.
