error[E0502]: cannot borrow `f` as immutable because it is also borrowed as mutable
--> $DIR/borrowck-unboxed-closures.rs:3:5

error[E0596]: cannot borrow immutable argument `f` as mutable
--> $DIR/borrowck-unboxed-closures.rs:7:5

LL | fn b<F:FnMut(isize, isize) -> isize>(f: F) {

error[E0382]: use of moved value: `f`

LL | f(1, 2);

= note: move occurs because `f` has type `F`, which does not implement the `Copy` trait
error: aborting due to 3 previous errors
