Daveus, Fredrik a ?crit :

I want to pass the result of a map_list_of call as an argument to a class ctor, but the only way I've managed to do this is by using some stuff from the assign_detail namespace.

Is there any other (more elegant) way of achieving this?

template<typename T> A(const T& t) : m_map(t) { } maybe? thanks, didn't try that one but tried the following and it compiles ok template<typename It> A(It first, It last) : m_map(first, last) { } / Fredrik This e-mail, its content and any files transmitted with it are intended solely for the addressee(s) and may be legally privileged and/or confidential.
