"Steve Russell said, look, why don't I program this eval..., and I said to him, ho, ho, you're confusing theory with practice, this eval is intended for reading, not for computing. But he went ahead and did it." Here is the point in the story where we need Norvig's annotation from PAIP (p. 777): "So the first Lisp interpreter was the result of a programmer ignoring his boss's advice." I like to think that the "ho, ho" in the original quote means that McCarthy appreciated this.
