I think the ability to use mathematical vectors should be in a library.
Perhaps more than one, with different aims.
So I'm more interested in making sure the core language supports writing
such a library, that works with existing types and operators more
seamlessly then in other languages, than about the actual semantics of a
mathematical vector.
