1, 2, and 3 are all fine. 1 would be useful if for some reason you wanted to change the behavior of Bar.agree at runtime. 3 has a few minor advantages: stack traces will print "agree" instead of "nod", it could be easier to modify later, slightly more self-documenting. And if you had been using super(), you could have avoided repeating the symbol Foo. But 2 is more efficient and less typing than 3. Option 4 is abhorrent.
