Oh, and slipping the new types in between 64 bit integers and floats is a
bit iffy. I've always been a bit bothered by numpy's dependence on the
linear order of the types as it is hard to maintain when new types are
added, and user types don't seem quite adequate. I don't know what we should
do here but it might be worth thinking about some other way of indicating
the relation/priority of the different types.
