Every STL container I know about gives you full-on value/copy semantics 
when you want it.  If I assign one map<> to another, there is no 
sharing.  Same for list<>, vector<>, deque<>, etc.  If you allow 
sharing, you are not offering value semantics (which is fine if that is 
what you are advertising).  The only time sharing is indistinguishably 
safe is for const containers.
