How should class objects created in betterC be destroyed

[zoe via Digitalmars-d-learn]

I customized object.d in -betterc mode and created NEW templates, 
with modules I can seemingly create classes without extern(C++) 
mode, and type conversions in function calls seem to work fine. 
But when destroy doesn't find a way to call the __xtdor() method 
of the corresponding subclass, is there any way to execute 
__xtdor() correctly
