What is module versioning in Perl?

Module versioning in Perl refers to the practice of specifying and managing the versions of modules to ensure compatibility and maintainability of code. It allows developers to indicate the functionality of their modules over time, helping users to avoid issues caused by incompatible changes.

In Perl, versioning is primarily handled using the `use` statement, which can include a version number to specify the minimum required version of a module. This ensures that the program will not run if an incompatible version of the module is used.

Here's an example of how to implement module versioning in Perl:

use My::Module 1.23;
