I did not know that any such class already exists. I did not find anything in RAA. But anyway, I have temporary withdrawn my RAA entry for the time I check this. My class was invented as I want to give another one an example for the power of callcc. As I did not find anything in RAA, so I did write it. Thanks you inform me about my mistake. > > Cheers, > Nat.
