Perl Modules: Import and Use Guide

To import and use modules in Perl, you can utilize the ‘use’ keyword. Here is a simple example demonstrating how to import and use a module:

use strict;
use warnings;

# 导入模块
use MyModule;

# 使用模块中的函数
MyModule::hello();

In the example above, we imported a module named MyModule using the keyword ‘use’, and called the hello function within the module.

Additionally, if you need to alias a module while importing it, you can use the following syntax:

use MyModule qw(func1 func2), {alias1 => 'func1_alias', alias2 => 'func2_alias'};

This way, we can use aliases to call imported functions instead of using the original function names.
