error[E0507]: cannot move out of `*x` which is behind a shared reference
  --> $DIR/borrowck-fn-in-const-a.rs:6:16

LL |         return *x
   |                ^^ move occurs because `*x` has type `String`, which does not implement the `Copy` trait
   |
help: consider cloning the value if the performance cost is acceptable

LL -         return *x
LL +         return x.clone()

error[E0507]: cannot move out of `y`, a captured variable in an `Fn` closure

LL | let y = vec![format!("World")];

note: `into_iter` takes ownership of the receiver `self`, which moves `y`

help: you can `clone` the value and consume it, but this might not be your desired behavior
