I parsed the Markdown files, converted them to markdown, extracted the <pre><code>...</code></pre> tags, and ran the inner code through JSHint (using Node.js, but I excluded all the warnings about missing semicolons)...

Not sure how many are valid, versus expected warnings for null type checking.

It may be that in the program, bats borrow code from birds even though in the testing oncology, Avian is very different from Animal.

Oncology or ontology?

It is a code smell to use programming language constructs to evaluate strings as code, especially where other metaprogramming facilities are readily available. Side effects include, but are not limited to, damaging syntax highlighting and a variety of code inspection / debugging tools.

In general, the string_to_proc method scares me and seems like fundamentally a bad idea.

I wonder if you really need push to return the pushed value ... what's the use case and why would you need that ? ... cause things could be much easier and faster just using Array.

    function StackMaker() {
      var a = [];
      a.isEmpty = StackMaker.isEmpty;
      return a;
    }
    StackMaker.isEmpty = function () {
      return this.length < 1;
    };

What do you think ?

Hi, I don't want to mess here with discussion about the article, but where can I do so?

The mentioned hacker news discussion page seems to be closed.

This would be even more awesome with a front-end besides github's.

I may in fact start working on such a thing.

There is something deeply broken about this.
