This week, I released a new version of Beam::Emitter. A lot has changed since the first releases, so here's some details on all the new features.
Beam::Emitter is a role for turning your classes into event emitters. Being an event emitter allows other classes to subscribe to important events from your object. Subscribers can use these events to perform additional tasks, transform your object's data, or otherwise extend and enhance your class. Beam::Emitter makes your class extensible by allowing you to provide specific places for custom code to run.
Since the 1.000 release last year, Beam::Emitter has gotten quite a few new features and bug fixes to make it easier to use and safer for your code.
