After some confusion and googling i found this very usefull explenation on stackoverflow, i thought its maybe valuable for others too:
Normally type checking is not done in Ruby, but instead objects are assessed based on their ability to respond to particular methods, commonly called “Duck typing”. In other words, if it responds to the methods you want, there’s no reason to be particular about the type.
