perl中数组和list的区别

perl cookbook 2th,chapter 4

In this chapter, we'll use the terms list and array as the Perl language thinks of them. Take ("alpha", "beta", "gamma"); that's a list of the names of the first three Greek letters, in order. To store that list into a variable, use an array, as in @greeks = ("alpha", "beta", "gamma"). Both are ordered groups of scalar values; the difference is that an array is a named variable, one whose array length can be directly changed, whereas a list is a more ephemeral notion. You might think of an array as a variable and a list as the values it contains.
