+error[E0525]: expected a closure that implements the `Fn` trait, but this closure only implements `FnOnce`
+  --> $DIR/closure-wrong-kind.rs:10:19
+   |
+LL |     let closure = |_| foo(x);
+   |                   ^^^     - closure is `FnOnce` because it moves the variable `x` out of its environment
+   |                   |
+   |                   this closure implements `FnOnce`, not `Fn`
+LL |     bar(closure);
+   |     --- ------- the requirement to implement `Fn` derives from here
+   |     |
+   |     required by a bound introduced by this call
+   |
+note: required by a bound in `bar`
+  --> $DIR/closure-wrong-kind.rs:6:11
+   |
+LL | fn bar<T: Fn(u32)>(_: T) {}
+   |           ^^^^^^^ required by this bound in `bar`
