Ack.

I meant the same, just used strange terminology, sorry. If I understand 
it correctly, Deref trait gives you "overloaded" dereference operator as 
well as implicit coercion in many cases, and I don't know if I want them.

Personally, I prefer the explicit style like:
```
let a: &AcpiInteger = /* ... */;
call_func(/* u64: */ a.val())
```

rather than:

```
let a: &AcpiInteger = /* ... */;
call_func(/* u64: */ *a)
```

The former feels clearer to me; the latter gives me "smart pointer" 
vibes and feels a bit confusing, because there are no smart pointers.

That said, I'm not a Rust expert at all -- so if you believe this change 
is better, I'll implement it your way.
