I would like to make a presentation during the next meeting on March, 19th. The topic I would like to talk about is classes' inheritance design in Ruby, singleton-classes (eigenclass) and how 'include' and 'extend' actually work. These things are basic but still very important in Ruby to understanding how all the magic works.
My German language is on "Hello World!" level, so I would like to speak in English, of course if it is possible.
