	Oh whoppie. He did carefully qualify his statements with a
	reference to current language + compiler technology.

	I am not so quick .. Actually, it took eight years :-). The
	article was interesting when I read it around 1980. Today, only
	some parts are somewhat interesting, and I think the rest is way
	out-of-date and uninteresting, at least for the languages I have
	been using. Check out the article and see for yourself. All of his
	very structured ways of using GOTOs to get out of loops etc. are
	covered by consistent language facilities, which is obviously not
	what is argued in the current GOTO discussion(?). As for other
	uses of goto for "optimization" purposes: things like "tail
	recursion optimization", "code motion out of loops" etc. are the
	type of things a good compiler can (or should) deal with. [In fact,
	there are languages out there, like SCHEME, where tail-recursion-
	removal and tail-call-to-jump optimizations are *generic* to an 
	implementation.  No-one using the language ever thinks about it.]

	Even some of Knuth's writings could become out-of-date don't you
	think ?? When was the last time you programmed in MIX ?? :-)
