Hi,
I need some help with using BOOST_TYPE_ERASURE_MEMBER. The example in the
tutorial works as described. But the interface binds to object by
reference. But if I change it to bind by value, I get a compile-time error.

BOOST_TYPE_ERASURE_MEMBER((has_push_back), push_back, 1)
void append_many(any<has_push_back<void(int)>> container) {
    for(int i = 0; i < 10; ++i)
        container.push_back(i);}

How can I fix it? I do want to bind by value.

Regards,
&rzej
