error: lifetime may not live long enough

| | return type of closure is [closure@$DIR/issue-53432-nested-closure-outlives-borrowed-value.rs:4:9: 4:15 f:&'2 [closure@$DIR/issue-53432-nested-closure-outlives-borrowed-value.rs:2:13: 2:23]]
| lifetime `'1` represents this closure's body

= note: closure implements `Fn`, so references to captured variables can't escape the closure
error: aborting due to previous error
