I don't know if I can really give you a satisfying answer because I don't understand it completely myself. Apparently scala allows what are called implicit conversions that allow conversion methods that take type parameters that are implicitly called in such a way that it seems like I can add methods to any existing class. http://www.codecommit.com/blog/ruby/implicit-conversions-more-powerful-than-dynamic-typing

One day I will understand this better and be able to give a better explanation.
