Macros are a wonderful feature.  For example, they
allow me to do something I've wanted to do for a long
time:

   #macro vector_str(V, N1, N2)
     concat(
       "< ",
       str(V.x, N1, N2), ", ",
       str(V.y, N1, N2), ", ",
       str(V.z, N1, N2),
       " >"
     )
   #end

I was hoping against hope that macros would find their way into
povray.

As a programmer, I desperately wanted to use functions to do
repetitive things.  I even wrote several povray preprocessors for my
own use.

How can it get any better?

So, I'd just like to say thanks also!
