I just don't use out parameters and avoid bare references altogether, const lvalue and rvalue references express idiomatically whether a parameter is to be copied or moved. Structured binding makes it trivial to consume returned tuples, so I don't find this a big issue.

You still have to write boilerplate to return them, though :-( But I agree it's better :-) Unfortunately, I'm on C++11 for this project, will be on C++03 for others :-(
