It appears I and a few other developers accidentially implemented
continuations without knowing it :-)
We had this problem with a scripting language used to execute interviews
(surveys). But sometimes you need to go back in order to a change a previous
answer. The logic was implemented by copying the interpreter stack. We also
worked with more refined ways where you do not copy unless values change and
more crude versions of rerunning the entire logic from start.
