  // step 2, just check that compiler understand what pass to bind2nd:
  binder2nd<const_mem_fun1_ref_t<bool,V,int> > b2 = bind2nd( pmf, 2 );

  // step 3, the same as step 1, but more intellect from compiler required:
  binder2nd<const_mem_fun1_ref_t<bool,V,int> > b3 = bind2nd( mem_fun_ref( &V::f ), 2 );

  vector<V>::iterator j = find_if( v.begin(), v.end(), b3 );
  CPPUNIT_ASSERT(j != v.end());
  CPPUNIT_ASSERT(j->v == 2);

  // step 4, more brief, more complex:
  vector<V>::iterator k = find_if( v.begin(), v.end(), bind2nd( mem_fun_ref( &V::f ), 2 ) );
  CPPUNIT_ASSERT(k != v.end());
  CPPUNIT_ASSERT(k->v == 2);
