Maybe template-specializations are considered zero parameters?
```cpp
template<typename T>
void foo(T value) {}
// here are 0?
template<>
void foo<double>(double value) {}
```
Or like this?
```cpp
template<typename T>
constexpr bool is_pointer_v = false;
// is this considered 0 because we explicitly specialize 'is_pointer_v'?
template<typename T>
constexpr bool is_pointer_v<T*> = true;
```
We can make condition `if Params->size() >= 1` so it's obvious we check it to
access the first argument and no more. Let it have 1, 2, 3, 4... parameters if
needed.
