There were a couple of issues here. First, the IterableContainerOf concept was testing if dereferencing an iterator of ContainerType<T> returns a value of type T. However, it should return a T&. Second, the constructor was trying to move values out of a constant reference to the container. We now accept both lvalue and rvalue containers.
