Geeky Friday: Extra-geeky, extra-fancy search and replace

Steve Yegge writes about Emacs 22 -- specifically about its internationalization support and its improvements to search and replace by regular expression. He writes:

Emacs 22 sports an amazing new editing feature that's had me drooling in anticipation since I first heard about it, maybe six or eight months ago. As you can well imagine, that's a lot of drool.

And what might the feature be, you ask? Well, they've enhanced M-x {query-}replace-regxp to accept lisp expressions to be evaluated in the replacement string.

He gives some cool examples of how this can be useful. (Sorry, non-geeks, this edition of "Geeky Friday" is over the top geeky.)
