+error[E0507]: cannot move out of `*inbounds` which is behind a shared reference
+  --> $DIR/issue-102389.rs:4:11
+   |
+LL |     array[*inbounds as usize]
+   |           ^^^^^^^^^ move occurs because `*inbounds` has type `Enum`, which does not implement the `Copy` trait

+error: aborting due to previous error
