Why doesn't this code work?

#declare fun = function { pigment {
  image_map {
    tga "face.tga"
    map_type 0
    interpolate 2
  }
 }
}

and then this in some object:

texture {
 pigment {
   fun
   color_map {
   [0  color White]
   [1  color Black]
  }
}

it keeps stopping between fun and color_map saying no matching } in pigment
vector function identifier found instad.

HELP!

Corey

probably

texture {
  pigment {
    function{1-fun(x,y,z).gray}
  }
 }

is enough

You want "pigment {function {fun(x, y, z)} ...}"...function names were 
never useable directly as pattern identifiers, though that would be a 
nice shortcut sometimes...
