The following simple snippet fails to compile:
template<typename T> struct any{ template<typename U> any(U){} };
template<typename... Ts, typename T>
T back(any<Ts>..., T);
int main(){
using _ = decltype(back<int>(true, 42));
}
With:
main.cpp:7:24: error: no matching function for call to 'back'
using _ = decltype(back<int>(true, 42));
^~~~~~~~~
main.cpp:4:3: note: candidate template ignored: couldn't infer template
