Overview

Perennial::Hookable

Perennial::Hookable provides a generic set of functionality for implementing simple block-based hooks / callbacks. On a class level, this makes it easy for you to do event driven programming in that code can be registered to be run when something happens.

Hookable differs from Perennial::Dispatchable in that it is designed to be lightweight / used for things like setting things up without all of the overhead of defining handlers / dispatching messages.
