Real-life case (from caff) to exemplify the short question subject:
$CONFIG{\'owner\'} = q{Peter Palfrader}; $CONFIG{\'email\'} = q{peter@palfrader.org}; $CO
It's a bad idea to put configuration data in compiled code, because it can't be easily changed by the user. For scripts, just make sure it's separated entirely from the rest and document it nicely.
