Callback::Cleanup

As a software review, let's talk about Callback::Cleanup, a Perl module that allows you to declare callbacks that clean themselves up.

First and foremost, this module is incredibly easy to use. Simply import it using "use Callback::Cleanup" and create your callback function along with a cleanup function that will be called upon object destruction. Alternatively, you can use Callback::Cleanup->new() to create your callback and cleanup functions separately.

What's great about Callback::Cleanup is its ability to provide syntactic sugar for callbacks that need to finalize somehow. Callbacks are incredibly useful APIs, but they can become messy if they don't have an end-of-life behavior. However, with this module, the cleanup code and callback code stay together.

Overall, Callback::Cleanup is a very simple yet helpful module that can streamline your callback processes. If you frequently use callbacks in your code, this module may just be worth trying out.
