    Yes, but feel free to play around with other options if you have a strong preference.

> Suppose X is an interface and Y an interface such that Y extends X
> The following code throws a compilation error (the outer class is annotated as @CompileStatic).
> {code}
> Set<X> set = new HashSet<X>()
> Set<Y> toAdd = ......
> set.addAll(toAdd)
> {code}
> However, the following works, which to me is inconsistent:
> {code}
> Set<X> set = new HashSet<X>()
> Set<Y> toAdd = ......
> for(Y y in toAdd) {
>   set.add(y)
> }
> {code}
