举个例子: 1与1是相等的(当然他们前提是类型是一样的)那么1和 new Number(1)也应该相等。

The top-level variable namespace (hash) is copied, but no attempt is made to perform a deep-copy of other structures (hashes, arrays, objects, etc.). Therefore, a foo variable referencing a hash will be copied to create a new foo variable that points to the same hash array. Thus, ...
In Perl, it is not required to specify the length of an array during the definition. Arrays grow or shrink dynamically. For Example, in the above array if we say $myarray [4] = 7; @myarray will grow in size and contain 4 elements (1,4,5,7). ...
In this chapter, we compare the Template Toolkit to other templating systems such as HTML::Mason and HTML::Template, describe how to install it, then show you what templates look like and how to process them. The goal of this chapter is to get you started—you should be able to install...
