I can confirm it's attempting to be a tiny CL subset. It has function namespace, symbols, simple numerics macros and backquote.<p>But error detection is non-existent: (ASSOC) crashed it, since it didn't check for arguments even.<p>It's at best, a Lisp <i>reader</i>, not interpreter, even if it does a few things right:<p><pre><code> (mapcar (lambda (x) (+ x x)) (list 1 2 3)) ==> (2 4 6) :-)
</code></pre>
