@David: Thanks for the fix with the missing userdata argument. I changed it a bit to check for arguments.length (number of arguments passed), since otherwise, it won't allow explicit passing of &quot;undefined&quot; as an argument. I also added support for closures and PHP-style object-function arrays, added an option to avoid eval (not on by default since eval() is more PHP-like in allowing calls to built-in functions), and provided support within array() for walk() as a chainable method.

Changes are in Git (see &quot;raw js source&quot;).

Line 21 doesn't make any sense, you are only passing userdata to the function, and userdata is undefined. Line 21 should be:
<pre><code>
eval(funcname + '(array[key] , key)');
</code></pre>
