For advanced uses (only), where you really need to optimize for rvalues passed to "input-only" parameters:
* If the function is going to unconditionally move from the argument, take it by `&&`. See [F.21](#Rf-consume).
* If the function is going to keep a copy of the argument, in addition to passing by `const&` add an overload that passes the parameter by `&&` and in the body `std::move`s it to its destination. Essentially this overloads a "consume"; see [F.21](#Rf-consume).

* In special cases, such as multiple "input + copy" parameters, consider using perfect forwarding. See [F.19](#Rf-forward).
