Note on 3.1, bug reports have gone from email to news,
so I am posting mine here.

The component operators don't work on 2-d vectors.  This
problem has existed 3.02 (at least).   A sample file :

----------------------------------------
light_source { 3 color rgb 1 }
camera { location 2 look_at 0 }
sphere { 0, 1 pigment { color rgb 1 } }

#declare uv = <1, 2>;
#debug concat("uv.u = ", str(uv.u, 0, -1), "\n")
#debug concat("uv.v = ", str(uv.v, 0, -1), "\n")
