	ii) In Algol W, there is no loop-exiting construct, which is a real
	   pain. 
/* ---------- */

I fear that the Algol W construct

	<T expression>	::=	<blockhead> (<statement> ;)* <T expression> end

or something to that effect has been forgotten about. You can thus write
your loop with exit as

	while begin
		stuff;
		predicate
	end
	do
		more stuff;

if you want to. Just another case of providing power through generality
rather than special cases...
