I was talking to my software engineering class about code reviews last week, while simultaneously thinking about how to replace the wiki parser in DrProject. Two birds one stone, I decided to review a wiki parser written in Python and keep notes on what I was thinking as I went through it. I've posted the result as a separate page on this web site; I'd be interested in comments and feedback. Later: Diomidis Spinellis posted a similar think-aloud back in 2004 that's worth reading.
