--> $DIR/issue-49824.rs:4:9

LL | || {

|
LL | / || {

| |_________^ returns a closure that contains a reference to a captured variable, which then escapes the closure body

= note: `FnMut` closures only have access to their captured variables while they are executing...

= note: ...therefore, they cannot allow references to captured variables to escape
