Heh...oops. :)

Apparently I got confused in the middle of converting from JS to Ruby.
(In my app I never actually used remove_thyself, so it wasn't been 
tested.)

Thanks for pointing that out. The correct code should be:

@@lookup[@o1].delete(@o2) if @@lookup[@o1]
@@lookup[@o2].delete(@o1) if @@lookup[@o2]

(or, if you like:
@@lookup[@o1] && @@lookup[@o1].delete(@o2)
@@lookup[@o2] && @@lookup[@o2].delete(@o1)
)


and has been updated to match.

(The 'delete' statement in Javascript removes a property from an 
object.)
