With pointer-like semantics, you have

flyweight<foo> f; flyweight g;

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

[...]

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::flyweightstd::string s("foo"); std::cerr << s->size() << std::endl;

to make sense, right?

Correct. Pointer semantics and pass-thru semantics cannot coexist in the same interface (not that I'm currently considering supporting either, anyway). For your case this is not a problemm, since you'll be using some incarnation of your custom poly_flyweight, which you can endow with whatever -> semantics you like (pass-thru, I presume).
