When you are ready to write an External Method:

     from Acquisition import aq_base

     def getClassName(obj):
       '''return the name of *obj* class.'''
       return aq_base(obj).__class__.__name__

As you need to access names starting with "_", you
cannot do it in TTW code but must use an External Method.
