"Is A" or "Acts As"

The article argues for the use of interface default methods in PHP by distinguishing between two types of object relations: the classic 'Is A' relation (contract) and the 'Acts As' relation (behavior). Using the PSR-3 LoggerInterface as an example, it explains how default methods can eliminate boilerplate code for convenience methods, making a case for their practical necessity in modern software development.
