 This error occurs when an attempt is made to mutate the target of a mutable
 reference stored inside an immutable container.
 
 For example, this can happen when storing a `&mut` inside an immutable `Box`:

 let mut x: i64 = 1;
 let y: Box<_> = Box::new(&mut x);
 **y = 2; // error, cannot assign to data in an immutable container
