Keyword 'template' confuses MSVC

Question

One of those \"which compiler is right\" questions about templates. Consider following:

template
class Container
{
public:
    template<         


        

Answer 1

You can simplify code by using trailing return type. No need for typename or template:

template<typename T>
template<typename V>
auto Container<T>::iterator<V>::operator++() -> iterator<V> &
{
    //do your thing
    return *this;
}
