Surely your reply to my post will be the basis of an Icon/Unicon tutorial, if I
ever get cozy with language. IMHO, novice, intermediate and advanced Tutorials
are sorely missing in this language(s). I taught myself Perl4 and Perl5 from
the wealth of information available on the Web. I'm currently doing the same
with newLisp.
The above blueprint that you've provided will get a person going without
creating "information overload", especially when the language paradigm is so
different - in key areas - than the mainstream languages.
I wish that you had posted the reply to the mailing, so that others might "clue
in". ;) Thanks a lot! Much appreciated.
