Well, with DIP1040 this is automatically the case for last uses.

So in your code example:

```
void phone(S s)
{
     S t = s;  // copy constructor
}
```

The comment is actually inaccurate with DIP1040. With DIP1040, this is a 
move.


Otherwise, maybe expose explicit moves. This is useful generally. Can 
just be `move(x)`, where `move` is either special, or is a function with 
a "move by default" attribute on its parameter, as we discussed previously.
