<h1><a href="../../../classes/Lisp.html">Lisp</a> Mixin</h1>
<p>
This module provides <a href="../../../classes/Lisp.html">Lisp</a>-like
functional notation. With this module it almost possibel to write real <a
href="../../../classes/Lisp.html">Lisp</a> code in Ruby.
</p>
<h2>Example</h2>
<p>
It’s hardly believable, but the following IS valid ruby code:
</p>
<pre>
(def accumulate (fun, x, list)
(if (null? list)
x
else
(accumulate fun, (fun.call x, (car list)), (cdr list))
end)
end)
</pre>
<p>
A real programmer can write LISP in any language… ;)

<p>
** Changed the name of Pair class to DottedPair. ** Added a new method
pair! which converts an array to a DottedPair. ** This is then used in car
and cdr to automatically convert arrays passed to them. ** Note: There may
be other places that pair! conversion is needed.
