Or by adding something else to trigger the instantiation of the right
specialization, e.g.

    using F = decltype(id<int>);

Slightly reduced (it doesn't matter if g has a deduced return type):


template <typename Tp> auto id() { }

template <typename T> void g(T) { }

int main()
{
    // id<int>;
    // using F = decltype(id<int>);
    g(id<int>);
}
