Right, copy_constructible<>, I forgot. Steve, did you consider adding copy_constructible<> to relaxed? Regards, &rzej 2013/12/6 Andrzej Krzemienski

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> 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
