| error[E0382]: use of moved value: `x` |
| --> $DIR/move-in-guard-1.rs:10:24 |
| | |
| LL | let x: Box<_> = Box::new(1); |
| | - move occurs because `x` has type `Box<i32>`, which does not implement the `Copy` trait |

| LL | (1, _) if take(x) => (), |
| | - value moved here |
| LL | (_, 2) if take(x) => (), |
| | ^ value used here after move |

| note: consider changing this parameter type in function `take` to borrow instead if owning the value isn't necessary |

| LL | fn take<T>(_: T) -> bool { false } |

| help: consider cloning the value if the performance cost is acceptable |
