Circular refs are easy to avoid with smart_ptr lib but idiomatically what you are really looking for is DynObj (and maybe RRef ) in the NoPtr lib (http://noptrlib.sourceforge.net). Strict ownership is ideal for pimpl and in particular your example of circular dependency, as supported by the NoPtr lib. Oliver
