I have all my books in boxes already (I'll move to Hamburg soon) so I cannot 
check myself: isn't the sourcecode which you can see on the very last pages 
of MEC++ actually an auto_ptr implementation? If not, is it really giving you 
explicitely shared semantics? An implicitely shared pointer (like 
QSharedDataPointer) is nice, but quite a hassle because it's perfectly 
possible that a lot of code which uses KSharedPtr actually depends on not 
detaching automatically.
