Concatenate compile-time strings in a template at compile time?

Question

Currently I have:

template  struct typename_struct {
    static char const* name() { 
        return (std::string(typename_struc

You could use something like this. Everything happens at compile time. Specialize base_typename_struct to define your primitive types.

template 
struct append {
  static constexpr const char* value() {
    return append::value();
  }
};

template 
struct append {
  static const char value_str[];
  static constexpr const char* value() {
    return value_str;
  }
};

template 
const char append::value_str[] = { suffix..., 0 };


template 
struct base_typename_struct;

template <>
struct base_typename_struct {
  static constexpr const char name[] = "int";    
};


template 
struct typename_struct {
  typedef base_typename_struct base;
  static const char* name() {
    return append::value();
  }
};

template 
struct typename_struct:
  public typename_struct {
};


int main() {
  cout << typename_struct::name() << endl;
}
