In same way - "ambient" should be removed because "it make sens only for 
applications where real ambience (radiosity) is impossible".

I agree thet env-maps are needed in few scenes. _but_ they can be created 
while adding more important path - functions based not only on <x,y,z> but 
alsow on normal (i.e. <nx,ny,nz>) of point. How about this idea ?

pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
