| error[E0594]: cannot assign to `fancy_ref.num` which is behind a `&` reference | |
| --> $DIR/E0389.rs:8:5 | |
| | | |
| LL | let fancy_ref = &(&mut fancy); | |
| | ------------- help: consider changing this to be a mutable reference: `&mut (&mut fancy)` | |
| LL | fancy_ref.num = 6; | |
| | ^^^^^^^^^^^^^^^^^ `fancy_ref` is a `&` reference, so the data it refers to cannot be written | |
| error: aborting due to previous error | |
