Can I add a plea to those who do have treasured regexen they're willing to share:

• download Regex::Common,
• see how easy it is to integrate your regexes into the module (using the pattern subroutine),
• do so,
• then send me a patch!

I very much want to update the module with new and useful patterns, but I don't have time to reinvent them. With your help and contributions, Regex::Common could become a significant community resource. BTW,

I'm also looking for someone to take on the maintenance and extension of the module. Japhy volunteered previously, but has more than enough on his regex plate at the moment.
