This should compile:
```
import core.attribute;
@mustuse struct MyError { }
struct S
{
MyError lastError;
this(int x)
{
this.lastError = MyError(); // Error: ignored value of `@mustuse` type `onlineapp.MyError`; prepend a `cast(void)` if intentional
}
}
```
Assignment seems to work, but initialization is not considered ignoring the value.
