As someone who uses the handle/body idiom quite frequently, I'd say it can be very useful.
But o for noncopyable classes (90% of the "pimpl candidates" in my projects) scoped_ptr works fine o in other places shared_ptr or intrusive_ptr work, but needs extra work to implement deep copy
No. The boost smart pointers are _not_ directly suitable for pimpls, because they don't propagate const.
This also makes them less useful in other contexts IMO. Just because I use vector<shared_ptr<T>>, doesn't mean that I want to give up const-correctness. And there is no efficent way to convert vector<shared_ptr<T>> to vector<share_ptr<const T>>. -Thorsten
