recursive algorithms!
(and plenty of other places too.)
(this was discussed in the endless C++/Ada rant a few weeks
ago. Slicing arrays, and using array attributes 'First, 'Last
obviate the need for extra parameters. Of course, the C++
enthusiasts didn't seem to be impressed. To work properly,
arrays need to be able to start from any index, of course.)
I agree with Duncan's point. It would be good to have
in the Vectors containers. I rather hoped Vectors could do
everything that Arrays could. I'm disappointed.
