There's a big difference between int and struct: the latter is an 
aggregate that may have member functions that have side effects. 
For example:

```d
getTemporary().doSomethingWithSideEffects();
```

That's a valid pattern. You might then say that's a different 
case than the assignment in your example, but `opAssign` for a 
struct can be overridden.
