I wrote a very similar tool one time:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;smizell&#x2F;geneva" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;smizell&#x2F;geneva</a><p>It is Lisp in JSON. I did it for fun, but thought it would a cool way to send instructions across the wire from the server to the client and back. Imagine validation rules that could be ready in any language with really very little parsing instructions.
