Despite what the naming conventions are, since the only thing, IMHO,
that interfaces are useful for, is determining if the object being
passed to a method complies and has methods/properties that can be used,
without having to write code to check if the object being passed
actually has all the desired methods/properties.
e.g. According to my understanding:
human, cat, dog are different objects, but they all have an IMoveAround
interface
So I know If I pass one of the objects to a method that it can use the
blueprints defined by the interface without something breaking, and have
each walk,crawl, Jump, etc... in their own way.
so shouldn't it be has-a? or it-has? or they-have? or is-able?
Maybe I am not experienced enough with solid OOP, but that's the way I
am understanding things right now.
