Esteban Küber ec98df4bb6 On unused assign lint, detect mut arg: &Ty meant to be arg: &mut Ty ...

help: you might have meant to mutate the pointed at value being passed in, instead of changing the reference in the local binding

LL ~ fn change_object2(object: &mut Object) {
LL |     let object2 = Object;
LL ~     *object = object2;
   |
```

This might be the first thing someone tries to write to mutate the value *behind* an argument, trying to avoid an E0308.
