本文介绍了Perl语言中列表和数组的基本概念及两者的区别。列表是有序的标量集合，而数组则作为变量用来存储这些列表。文章还强调了尽管这两个术语常被互换使用，但它们之间存在本质差异。

If a scalar is the "singular" in Perl, as we described it at the beginning of Chapter 2, the "pulural" in Perl is represented by lists and arrays.

A list is an ordered collection of scalars. An array is a variable that contains a list. People tend to use the terms interchangeably, but there's a big difference. The list is the data and the array is the variable that stores the data. You can have a list value that isn't in an array, but every array avriable holds a list (althonght that may be empty).

Since lists and arrays share many of the same operations, just like scalar values and variables, we'll treat them parallel. Don't forget their difference thongh.
