//PUZZLE: This code compiles, but requires an ugly double argumetn on line 27. How to change the code so
//this is not required, yet the TMagic type is still automatically deduced?
//
//- Dont want to make DoSomething virtual
//- compile with gcc -c test.cpp


template<class T> struct Converter {};

struct TheMagicTypeToFind {};

struct MyConverter : Converter<TheMagicTypeToFind>  //I want to store the magic type here
{
   void DoSomething();
};

template<class TMagic, class TConverter>
static void MyFunc(TConverter converter, Converter<TMagic>& onlyUsedForArgumentDeduction)
{
  TMagic magic;
  converter.DoSomething();
}

static void Main()
{
  MyConverter converter;
  MyFunc(converter,converter);
}
