If it wasn't for the following, I'd agree with you:

template<typename T, int I> 
auto foo(T t, T* pt, double a, std::string b){
 //...
}

but how on earth would you do _that_ with typeof?

template<typename T, int I>
typeof(foo<T, I>(T(), 0, 0.0, "")) // yuk, yuk, yuk
foo(T t, T* pt, double a, std::string b){
  // ...
}

To me function declarations are the main argument for auto: and once
you have it there, you might as well have it in

auto x = foo<int, 1>( /* bla */ );
