I've got it, something weird happened to my copy constructor. 
This was my original attempt and was ignored (didn't run in the 
copy constructor):

```
this(T)(ref return scope T original)
if(is(T == RVector!(Type)))
{
     //... code ...
}
```


But this now works:


```
this(ref return scope RVector!(Type) original)
{
     //... code ...
}
```

No idea why. `Type` is a template parameter of the object.
