Name the most widely used bytecode interpreter or virtual machine. Sun's JVM? Adobe's Flash? .NET and Mono? Perl? Python? PHP?

I love Perl because of its expressiveness. You can write incredible code and it feels just so natural compared to other languages. Here are 8 secret Perl operators that I often use. Only one of them is a real operator (first one). The others are syntactic tricks that make them look like operators but they are not…
