  Well, you could count the amount of 1's in the string. I think that should
be the correct answer (I haven't tried what happens when you do a (V=V) with
V being a 2D vector, but I think it should return <1,1>).
  Of course that's even slower because you'll have to call substr() at least
two times. Don't know if that matters in practice (after all, the string is
very short).

  Perhaps something like:

#macro VectorSize(V)
  #local tmp = vstr(5, (V=V), "", 0, 0);
  (2 + (asc(substr(tmp,3,1))=49) + 2*(asc(substr(tmp,5,1))=49))
#end

#declare V1 = <1,2>;
#declare V2 = <3,4,5>;
#declare V3 = <6,7,8,9,10>;

#debug concat("Size of V1: ", str(VectorSize(V1),0,0),
            "\nSize of V2: ", str(VectorSize(V2),0,0),
            "\nSize of V3: ", str(VectorSize(V3),0,0), "\n")
