1 error[E0373]: closure may outlive the current block, but it borrows `x`, which is owned by the current block
2 --> $DIR/unboxed-closure-region.rs:8:9
5 | ^^ - `x` is borrowed here
7 | may outlive borrowed value `x`
9 note: block requires argument type to outlive `'1`
10 --> $DIR/unboxed-closure-region.rs:6:9
14 help: to force the closure to take ownership of `x` (and any other referenced variables), use the `move` keyword
