Currently, cameras placed inside object or union statements will halt the render with an error. Take for instance the following case:

#local temp_camera_1 = camera
{
  orthographic
  location  z*-12
  direction  z
  up    y
  right    x*image_width/image_height
  scale    32
}

#local temp_light_1 = light_source
{
  0
  color rgb 1
  translate <-30, 30, -30>
}

#local temp_light_2 = light_source
{
  0
  color rgb 1
  translate <-30, 30, +30>
}

union
{
  object {temp_light_1}
  object {temp_light_2}
//  camera {temp_camera_1}  // doesn't work!!!
}

//object {temp_camera_1}  // doesn't work!!!
camera {temp_camera_1}  // works!!!

Changing this behavior would make it possible to more easily apply transformations to scene objects and the camera at the same time in situations where the scene’s frame of reference is in motion relative to the rest of the scene, for instance in animations.
