Cycles: How do I exclude the Environment Texture from reflections? In a Cycles scene I have an equirectangular image serving as an Environment Texture background (set in the World settings).

I have a glossy object being partially lit by the Environment Texture, as well as getting reflections from it.

Is there a way I can exclude the Environment Texture from affecting the glossy object completely? I want the image as background wallpaper only. The glossy object should be affected by other objects and lights within the scene: everything except the Environment Texture.
You could use Is Glossy Ray and a mix node in your environment material, but it might look weird..
