Principially I would like to contribute. I have to admit though, that I
have never contributed to boost before.
In my oppinion it should suffice to add move constructors/ move
assignment to /utility/value_init.hpp, which I could do.
How do we go on from there? Shall I submit the modified header file to
this mailing list for review or what is the usual procedure?
