| error[E0596]: cannot borrow `r` as mutable, as it is immutable for the pattern guard | |
| --> $DIR/issue-27282-reborrow-ref-mut-in-guard.rs:12:25 | |
| | | |
| LL | ref mut r if { (|| { let bar = &mut *r; **bar = false; })(); | |
| | ^^ - mutable borrow occurs due to use of `r` in closure | |
| | | | |
| | cannot borrow as mutable | |
| | | |
| = note: variables bound in patterns are immutable until the end of the pattern guard | |
| error: aborting due to previous error | |
