Do you actually -need- this variable? In other words, do you need 
objects to be able to decide at runtime if they are going to be rooms or 
NPC's? If not -- why not have them inherit market objects that declare a 
nomask function object_identity() or somesuch.

Then you can mask compile_object() in your second level auto object, 
making it atomic, perform the ::compile_object(), test for the existence 
of the marker function using function_object(), and if it is not there, 
cause an error (which will roll back the compilation itself).
