in thread meaning of /o in regexes
And of course if you happen to run your regex in a Perl script in an Apache Webserver with mod-perl your regex gets instantiated to whatever value the first user put into it as your script gets compiled only once for an untold number of requests.
It can make for a lot of interesting bugs!
