The iterators fortune!norskog describes are almost identical to the
generators of CLU (someone more familiar with CLU please correct me if
I'm wrong).

On the other hand, the full TO loop syntax from ALGOL68 (as I remember it)
is:

	[FOR var] [FROM count] TO count [STEP size] DO
		fragment
		OD

The only required part was the TO count, which caused fragment to be
executed count times. All the others could be added at will, giving
starting point, step size, and a variable if you needed it in the loop.

I like it much better than any other counter/loop I've seen. If only it
didn't have that DO OD pair.
