where "use warnings" burns (Score:2)

by merlyn (47)
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).

  My interpretation....was that $country wasn't dealing with definedness, but was instead determining whether or not to use brackets. If there's nothing there, "[]" might look stupid, so you don't want to put the brackets; and if it's 'gbr', you don't want anything there for whatever reason.
