I agree with todd8, but would like to add that the next paragraphs were not added for two simple reasons: the quote itself was already too long and I felt it summarizes well enough the gist of the argument: programming languages should not allow 'clever' tricks.
But, lets discuss the 'for clause' and 'do loop': these constructs were made specifically for one kind of simple loop. It is not a systematic solution for an iterative process. To me it seems Dijkstra specifically aims for languages such as LISP (which, with the renewed interest from Clojure is one of the most oldest successful (semi-) functional programming languages).
