That's correct unless there's nothing wrong or inefficient about how I use (show...) within my (show> ...) method to display the data of a relation instead of it's external symbol. > > The 'edit' function is remotely doing that, in that it shows the > class(es) of the object(s) in a relation (and also decodes calendar > dates).

I like this idea of a dumb text field just displaying the data. Can you elaborate on this? How about using > the gui 'repl' function (which opens an interactive REPL in the browser, > be careful about security issues!!) and then your 'show' from above? ;) Cool! I didn't even know about this. I may use it for debugging but the shell REPL is fine and I'm too paranoid worth security to let anyone else have a REPL.
