I also loved this article and voted ++ for it. What really makes it outstanding (for me) is that it is clear, concise, and not so hideously technical that I can't understand it.

I would like to know a lot more about the internals of Perl, but some of the articles that I have read have assumed such a high level of knowledge on part of the reader that I just put the article down and pretend to pick lint off my sleeve or something (and some have erroneously assumed a high level of knowledge on the part of the author).
lhoward: I love your posts, keep 'em coming.
