Say I have a fusion vector of different types with a constructor taking an int. eg:

fusion::vector< std::vector<double>, std::vector<int> >

and I have such a type as a member of a class foo. Now class foo has a constructor taking an int and I want to forward this parameter to all constructor of my fusion sequence member.

Is there a C++03 way to do this with minimal amount of copying ?

Here is my very limited attempt without all the Boost.Preprocessor mumbo jumbo: https://gist.github.com/2627795 If your sequence is move enabled (move ctor and move assignment, possibly trivial) this should create your minimal amount of copies
