Hello Walter,It's handy for things like rewriting ++e so it can be used more than once but is only evaluated once:(tmp = ++e, tmp)Uh? How is that different from "++e"You can then use tmp more than once with only one increment of e.how does that differ from using ++e the first time and then e for the other times?
1. e may be a global 2. ++e may be a more complicated expression with side effects
