Yes, even I could follow that.

We could use this example and one that shows how to write it for 
specifying different vectors. I assume from reading this it would be

((make-vector 1 '( ... )),
(make-vector 2 '( ... )),
(make-vector 3 '( ... )),)

Or something - but then again, I am not the target audience for the IR :)
