Overloading c++ typecasting (functions)

Question

Using C++ style typecastings (all 4) look exactly like some function template. e.g.

template
TO dynamic_cast (         


        

Answer 1

Pointer conversion with dynamic_cast, reinterpret_cast and static_cast have well defined meanings and it is probably better not to allow overloading.
It would be a pain to allow users to change the meaning of const_cast.

Only object type casting remains.

struct A
{
  A() {};
  template 
  A(FROM&)  {
    std::cout << "Casting to A \\o/" << std::endl;
  }

  template 
  operator TO()  {
    std::cout << "Casting from A \\o/" << std::endl;
    return TO();
  }
};

then

  int i; A a;
  A toA = static_cast(i);  //  Casting to A \o/
  int fromA = static_cast(a); // Casting from A \o/

Hopefully you have better use cases than mine :)
