[mod_python] vampire.importModule from module import function/class?

Are there any special options that can be given to 
vampire.importModule() that duplicates "from module import 
function/class" style imports or should I just stick to the long dotted 
notations for calling these functions/classes? It sure would be nice to 
only have to load the code for the functions/classes I needed.

Thanks,
Bram.
