I guess I knew that, sorry for the dumb question - the real 
question I had is whether one should use `isPOD` instead of 
`isCopyable` in cases

```d
             static if (__traits(isCopyable, Element))
                 insertAt(element, index);
             else
                 insertAt(move(element), index);
```

because that avoids any potential call to the copy-constructor 
and destructor of `Element`. Afaict, one should.
