I was wondering if boost has considered a smart pointer that is similar to
scoped_ptr but supports deep copy semantics. This would be useful in classes
which use the pimpl idiom, as a common way to program these classes is with
a scoped_ptr or auto_ptr, but then a copy constructor and copy assignment
operator needs to be defined. Herb Sutter worked on an implementation at
http://www.gotw.ca/gotw/062.htm, so there's precedent. Is there any interest
for this?
