($a,$b,$c) X ($x,$y,$z) ---> ($b*$z - $c*$y, $c*$x - $a*$z, $a*$y - $b*$x)

use classic_vectors; # perhaps.

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.
