I very much like the fact that MySQL allows you to embed comments into SQL statements. These comments are extremely convenient, because they are written into MySQL log files as part of the query. This includes the general log, the binary log and the slow query log. Maatkit includes tools which interact with these logs, including mk-query-digest. This tool, in particular, has a very nice option called --embedded-attributes which can process data embedded in query comments.
The support for embedded attributes makes some cool tricks possible. Peter and I co-presented a talk at this past MySQL Conference and Expo. In this talk I presented my

You guys are generating an amazing amount of feedback on your blogs. Matt mentioned in the April Wrap-Up that there were 8.6 million comments! Comments are flying in every second of the day.

Really cool to see Chris taking up blogging as well 
He has written nice little example about inserting comments into queries to distinguish the client’s IP when they are funneled through the proxy. Reading the comments about this little trick making the query cache not work, I couldn’t help thinking that those are wrong. I vaguely remembered that in some recent version this shortcoming was fixed, so I decided to run a little test on 5.1.30 to verify:
