What is package and namespace in Perl?

In Perl, a package is a way to group related variables and subroutines together under a single name. It serves to create a separate namespace, allowing for the encapsulation of code and reducing the likelihood of name collisions. Each package can be thought of as a module, and it can contain its own set of variables, functions, and other packages.

A namespace in Perl is a container for identifiers such as variable names, function names, and class names. It helps to organize code and prevents naming conflicts between different parts of a program. By using packages, you can have multiple items with the same name in different packages without conflicts.

Example

package MyPackage; sub my_function { print "Hello from MyPackage!\n"; } package main; MyPackage::my_function(); # Calls the function from MyPackage
