Some of that would probably have to stay.  Consider these two problems, which
wouldn't be caught on such a prepass but probably should be:

Problem 1:
----------
#macro MyMacro( foo, bar ) 
  object {foo texture {bar}}
#end

MyMacro(1,2)

Problem 2:
----------
#declare a=0;
#while (a<1 ) 
  #if (a<.5)
    sphere {10*a*x,1 pigment {color rgb 1-a}}
  #else
    sphere {10*a*x,1 pigment {color rgb a}
  #end
  #declare a=a+.1;
#end
