Thanks you both very much for answering.

Just to clarify some more: isn't "s1 = ss1" similar to something 
like:

```d
     const(S1) s1;
     S1 ss1; // ss1 is now S1.init
     S1_copy_construct_const_in_const_out(ss1, s1);
```

If this is the case, the compile error is expected, but 
why/how/where do "implicit qualifer conversions" apply here?

Thanks again,
