A good point - the obvious solution, from a user's point of view, would be that
scale <0,0,2> would generate an error (not a warning), but scale z*2 wouldn't,
it would just silently expand to <1,1,2> - however, from a programmer's p.o.v.
(sic) I can see that this might be impossible if the expansion to a full vector
is done before the vector operation itself...
