You can think of an object's data as a monad's data, and the methods in the objects in a hierarchy as the various monadic functions which operate on that data. In a typical functional language the monadic functions and their arguments do not have any hierarchical relation. >> If can code classes but if you are implementing (all) in an imperative >> way, I mean line by line telling the computer how to do something >> instead of code what you just want, you may not are thinking in terms >> of Objects.
