The challenge: try to rewrite the last two lines of this code 
without a typedef (typedefs should never be required, right?).

//////////////////////////////////////////////////////////////
struct B
{
  void Foo(short);
};

struct A
{
  static void (B::* var)(short);
};


typedef void (B::*q)(short);
q A::var = B::Foo;

//////////////////////////////////////////////////////////////

You can write it without a typedef like this:

void (B::* A::var)(short) = B::Foo;
