Bruce,

Guilty. I'm a bit of a regex geek, but I also tend to use advanced 
expressions (like positional assertions), even when simpler ones would do 
the job, just to stay in practice. You'll find these things become second 
nature if you use them all the time, even if they look like gibberish at 
first glance.

Also, while the documentation that comes with the PCRE library (which you 
can download and install for free) is very extensive and useful, I probably 
learned most of what I know about regular expressions just from using 
BBEdit and reading the User Manual. The "Searching with Grep" chapter is a 
clear and succinct guide to the most useful patterns and concepts, and the 
Find/Replace dialog provides a great environment to practice using them 
painlessly.
