I guess it's not mentioned, because it is not necessary, and at least to my knowledge, most people will be using C-x C-e (eval-last-sexp) and C-M-x (eval-defun) in the *scratch* buffer. Using a REPL, when you can evaluate any part of a buffer seems like a step back to me. But I guess there would be no harm in mentioning it. -- Philip K.
