in reply to Why would one want in a regex a class with only a single entry?

Additionally to the comments above and not entirely perl related: I often use 1-character classes in Unix when grep-ing for processes:

ps -afe | grep '[m]yprocess'

People who don't know this trick usualy type:

ps -afe | grep 'myprocess' | grep -v grep

s$$([},&%#}/&/]+}%&{})*;#$&&s&&$^X.($'^"%]=\&(|?*{%
+.+=%;.#_}\&"^"-+%*).}%:##%}={~=~:.")&e&&s""`$''`"e

    Is that a timing thing? Because, if it is, that little trick is pretty diabolical. :)
