it looks like the primitive type doesn't work with eq, eqv or equal.
perhaps I have to write a primitive-eq?

the example script works the other way round, checks if the mouse is over
an object and only does something if it is. this is due to the fact that
mouse-over is slow, and you should only call it once per frame (maybe
caching the result per-frame would be a good idea)
