Thinking about 3D vectors as objects, I'm sure a C++ application would
struggle with lots of tiny objects like that, and it would certainly
cause a lot of allocation churn unless some clever reusing was going
on.  Surely the userdata needed here is an _array_ of 3D vectors, to
efficiently handle the storage and processing of many vectors?
