error[E0382]: use of moved value: `b`
  --> $DIR/borrowck-consume-unsize-vec.rs:8:13
   |
LL | fn foo(b: Box<[i32;5]>) {
   |        - move occurs because `b` has type `Box<[i32; 5]>`, which does not implement the `Copy` trait
LL |     consume(b);
   |             - value moved here
LL |     consume(b);
   |             ^ value used here after move
   |
note: consider changing this parameter type in function `consume` to borrow instead if owning the value isn't necessary
  --> $DIR/borrowck-consume-unsize-vec.rs:3:15

LL | fn consume(_: Box<[i32]>) {
   |    -------    ^^^^^^^^^^ this parameter takes ownership of the value
   |    |
   |    in this function
help: consider cloning the value if the performance cost is acceptable
   |
LL |     consume(b.clone());
