In a new blog post today, Terry Chay shares some of his thoughts on the "eternal pointlessness of the PHP compiler" due to a recent resurgence.
Here is an recent e-mail exchange that puts it in its place (along with some information about code browsers and documentors and a lot of confusion on my part). I don't think anyone is going to mind me posting these since the only one who comes off as an idiot is me.
In the course of this exchange involves mentions of different efforts through out time to compile PHP code, including a proof of concept put together by Marco Tabini. He also includes the responses for each of the other people he CCed on the email (like Marco and Jeff Griffiths - Active State and Haiping Zhao - Facebook).
