I was scanning a page on references and this caught my eye
A reference is a scalar value that refers to an entire array or an entire hash (or to just about anything else). Names are one kind of reference that you’re already familiar with. Think of the President of the United States: a messy, inconvenient bag of blood and bones. But to talk about him, or to represent him in a computer program, all you need is the easy, convenient scalar string “Barack Obama”.
Gotta love Clear examples like this 🙂
Also; Interesting to read why some perl things are the way they are..
