Re: Vector cross product

Agreed that it's simple, but the dot product is even simpler and is

I think the point which Brian was trying to make -- and I apologise in
advance if I'm wrong -- is that a dot product is general and applies to
vectors of any length as the sum of the pairwise products of the
elements of those vectors. In contrast, the vector product you're
referring to only exists when the vector is of length three. As such
it's a specialised case and not worth including in the library.
