Priority when choosing overloaded template functions in C++

Question

I have the following problem:

class Base
{
};

class Derived : public Base
{
};

class Different
{
};

class X
{
public:
  template 
  stat

I found a VERY easy solution!

class Base
{
};

class Derived : public Base
{
};

class Different
{
};

class X
{
private:
  template 
  static const char *intFunc(const void *, T *data)
  {
    // Do something generic...
    return "Generic";
  }

  template 
  static const char *intFunc(const Base *, T *data)
  {
    // Do something specific...
    return "Specific";
  }

public:
  template 
  static const char *func(T *data)
  {
    return intFunc(data, data);
  }
};

This works great and is very slim! The trick is to let the compiler select the correct method by the (otherwise useless) first parameter.
