I think explains a lot of the polarised reactions people have towards Perl. It's trivial to understand the difference between the scalar var $foo and the array var $foo[0] if someone explains it to you or you read it; but if you're trying to Google-as-you-go, you don't even know what to search for. Those in the former group are more likely to find Perl delightful, while to the latter it's just frustrating.
