Well, SUVs are much popular now than they were 10 years ago. For sure, cars are still around, but some of them have been replaced by SUVs. But you are right, SUVs will never completely replace cars.

So to extend my question onto your analogy: If Perl were an SUV, would SUVs be getting more popular or less popular?

$PM = "Perl Monk's";
$MCF = "Most Clueless Friar";
$nysus = $PM . $MCF;
