Whatever it is that you want to achieve with this environment mapping
can almost certainly be achieved with the existing features.

One method would be to paint your environment picture onto a sphere
which surrounds your scene. Set no_image on the environment sphere and
no_reflection on the objects in your scene that you don't want to be
reflected.

Another method would be to use a layered texture on your object. One of
the layers would a mirror image image_map of the environment.

But to produce the best result, and using the simplest code, I'd suggest
actually putting your environment into the scene and allowing it to be
truly reflected. Environment mapping is an ugly kluge for systems that
can't manage real reflections.

By the way, the spell checker on your news client seems to be severely
broken.
