Macro function with several lines for the parameter?

Question

In C++, I need to defined a macro. That macro would take as parameter a \"block\" of code.

Can we safely use several lines of code as parameter of a macro fu

In C++ you should use a functor! ;)

struct ninja
{
  void operator()() const
  {
    int k = AFunction();
    k++;
    AnotherFunction( k );    
  }
};

template 
void do_something(Functor const& f)
{
  f();
}

template 
void do_otherthing(Functor const& f)
{
  f();
}

int my_function()
{
  ninja foo;
  do_something(foo);
  do_otherthing(foo);
}
