There's currently a somewhat misleading (I claim) error message that states
"error: use of moved variable". I claim this should instead be "use of moved
value". In particular, there's no problem with using the variable; in
particular, you can mutate it to some new value. For example, this code is
adapted from the borrowed pointers tutorial:
fn example3() -> int {
struct R { g: int }
struct S { mut f: ~R }
let mut x = ~S {mut f: ~R {g: 3}};
let qqq = x;
let y = &x.f; // Error reported here.
x = ~S {mut f: ~R {g: 4}}; // ... but this line is fine!
3
}
FWIW, this error message actually misled me; I'm not just being a PL pedant :).
This change seems significant enough that I should ask, rather than just making
a change….
