With pointer-like semantics, you have

flyweight<foo> f; flyweight<foo*> g;

f->x=0; // OK g->x=0; // error

This is again a bad example because stored elements are treated as const :-) Consider instead

std::cout<<f->x; std::cout<<g->x;

for instance. You get the idea, anyway.

Yes, I think this time I see what you mean. You're proposing boost::flyweight<std::string> s("foo"); std::cerr << s->size() << std::endl; to make sense, right?
