Nevertheless an interesting idea. Unix pipes are basically concatenative, I've often thought how much mileage you could get out of going more in this direction.

Having said that. This has a lot of forth in it. (Dup, over, rot) I'm not sure the forth way, of passing options in the stack would necessarily work so well in a shell.

I wish I were half as productive as Devine Lu Linvega. Perhaps I should get a sailboat and spend my time hacking without distraction, but I am not a fan of the seas.
