I wonder...  why do you say that?

To the best of my knowledge the signature of operator++() and
operator++(int) are:


   13.5.7  Increment and decrement
   [...]

   class X {
   public:
      X&    operator++();     // prefix ++a
      X     operator++(int);  // postfix a++
   };


Besides...i am not too sure why you say the following code should not be
legal.  I beleive it does produce the expected result/output:

   0, 1, 30, 40, 50
