Loopt is my pet programming language. It's a cross between perl, VHDL, and lisp. I think it could turn out to be useful. Maybe for teaching programming? Nah, it would probably corrupt the minds of new programmers worse than cobol.
So far, there exists a spec, and a couple of examples.
Version 1.1
spec (postscript)pdf version removed until I figure out how to make it happy with .eps figures.
Version 1.0
spec (postscript)spec (pdf)
I think it even meets most of the guidelines set out here
There now exist some example programs! note that these use some stuff that's not quite in the spec yet. I'll try to fix the spec shortly.
bridgekeeper.loopt - asks some questions
rpn.loopt - a simple RPN calculator!!
