Don't listen to most of the people here. Perl? What are they talking about. It is a concatenative shell. Think forth.

That said, the examples could be better explained just like you did here now. The examples are not bad but things like the f iterator probably needs some explaining.

I really like the idea. A more simple shell language is something I've wanted. Either lisp or forth would work but the basic issue is that bash and the rest are so complicated and with so many special things you have to know. Doing anything other than most basic shell scripts is horrible.
