Here is solution for you:
mb = module_builder_t()
for cls in mb.classes():
#find out all classes with the same name
other_classes = mb.classes( cls.name )
other_classes = filter( lambda other_cls: not other_cls is cls )
for other_cls in other_classes:
#use parent name to mangle the final name of the class
#You can implement any logic you want here
other_cls.rename( other_cls.parent.name + '_' + other_cls.name )
You also can do this for all classes - add namespace name to the class name.
Another solution could be to create module per namespace + one module
that will contain common stuff. If you will decide to go with this
approach be sure to read this:
