There was a lot of 'bad mouthing' of iter, leave, etc. yesterday.  How
would you get out of a DOW 0=0 without using them?

How is this any better than any better than a 'leave'?

I can certainly understand the arguments against leave/iter.  That said, I 
find them to be useful in some cases, mostly the type of thing that Wes 
was talking about - if user input doesn't validate, redisplay the screen 
before processing the input.  I'm sure that there are other ways to 
accomplish this than leave/iter, but I suspect that they could easily 
become at least as confusing as the use of leave/iter.  This is probably 
one of those things where if you are going to use a leave or iter, it is 
worth thinking about whether you can redesign the code in question. 
Sometimes the answer will be "yes", sometimes "no", sometimes "yes, but 
more work than it's worth".
