Joe Corcoran chce zrobić o tym prezentacjęBetter Composition with Traits
This talk will explain the concept of traits, specifically the model described in the 2006 paper Traits: A Mechanism for Fine-grained Reuse by Ducasse et al.
We will take a look at differing trait implementations in some other languages, which specific everyday design problems traits solve and how they differ from Ruby modules as a method for code reuse.
Finally we will explore how some features introduced in Ruby 2 allow us to implement Ducasse's traits in Ruby and how to compose a class without touching the class hierarchy at all.
