The first version of the Cat interpreter is available online at
http://www.cdiggins.com/cat.zip . Cat is very similar to Joy, and the
interpreter is written in C#. I have released into the public domain, so
please feel free to hack it. I plan on diverging from Joy more in the
future, with the addition of macros and type annotations.
An introduction to Cat is available at http://www.cdiggins.com/cat.html .
