  I have noticed this and I have always liked this property. It can be
an extremely useful property sometimes.
  For example: An include file may set a camera given some parameters (say,
an include by Colefax). However, this include doesn't support everything a
camera could support (eg. normal perturbation of the camera rays). Fortunately
this doesn't matter, as I can call the include file, which sets the camera,
and I can afterwards add the extra stuff to the camera, and everything works
just great. I mean, like:

#declare some include file parameters
#include "fancy_include.inc" // this sets the camera according to the params
camera
{ normal { bumps .5 scale .1 }
}

  This is incredibly versatile and useful. Disallowing this property would
certainly deprive povray of a great feature.
