I'm not sure. The opinions of people like Kenneth are quite valuable here,
because they are still at a place that those of us who write code fluently can
only dimly remember. I honestly can't remember if I had more trouble with for
loops than while loops when I was learning to program. From where I'm standing,
it could easily be argued that for loops are the more challenging.

Well, true. If we have both, then it's not an issue :-)


As an aside, I think there *has* to be a legacy parser (as I believe clipka
suggested). There is just too much useful stuff that will break, and users who
will either stick to pre-4.0 versions or stop using POV completely. Also,
having a simpler, more 'approachable' SDL will encourage users in, as it does
now. I see no problem in the old-style option being more restrictive; this
will, in turn, encourage the more confident user to move on to the new. Of
course, we will need plenty of code and tutorials posting here in the early
days to help everyone out!

(Don't get me wrong, I'm all in favour of a new SDL - indeed, I'm salivating at
the possibilities!)
