unset(Perl)
Dear Perl community, I just wasted 15 minutes of my life trying to figure out how to get the index of a particular element in an array. Turns out I have to write a for loop to walk through the array. This is insulting. Seriously, it’s 2007. If at this point in time you’re still defending your beloved language and/or using words like “elegant” or “quick” when describing Perl, you’re bat shit crazy.
