The issue is that you can't convert const (or immutable or
mutable) to inout implicitly, and the member variable is inout
inside an inout constructor. Therefore, there's no viable copy
constructor to call for the member, and the outer copy
constructor cannot be generated.
I'm not quite sure I follow this. Are you saying that the
constructor call is typechecked as if it were written like this:
```d
this.field = this.field.__ctor(rhs.field);
```
...and not like this?
```d
this.field.__ctor(rhs.field);
```
Because I can see how the first version would involve an
const-to-inout conversion, but the second version looks like it
ought to work.
