  • My guess is that sometimes, $country is undef. And because it might be, the author writes horribly perverted code just to avoid getting an irrelevant warning message. This is the downside of warnings.

    And given that, I'd have written this code as: $country = $country eq 'gbr' ? '' : uc $country; See how much clearer it is when you stop worrying about stupid warnings? Don't be pedantic about warnings. Stop using them when they make your code look ugly. (/end rant).
