Hal, too bad you couldn't make the Ruby Conference.  Avi Bryant
presented a very similar example based on the Borges (spelling?)
library.  His example was a console app using "ask" and "display"
methods to prompt and get data.  By changing two lines in the file (the
require line and the call to "main"), he was able to convert the example
from a console app to a web app.  Very cool.

The really interesting part is how he supports the back button in web
browsers.  Essentially this requires backing up the procedural program
to an earlier state ... which is a perfect use for continuations.

I see another response to your request mentioned the squeak verion of
Iowa (which is also by Avi).  Is the squeak version similar to Borges?
