Alphabet starting with M? Hey, prescriptivist dingdongs, you can’t just say there is now apparently an alphabet that starts with M! Those things don’t exist in vacuum - if you make something like this up, you have to go all the way and define such an alphabet clearly!
Rules mean nothing unless they clarify established language use conventions! Which is why I think descriptivist approach is better in most cases.
Or: “The algorithm and data structure theory stuff is still pretty relevant. However, all of the examples are written in a language no one really uses any more. If they can get away with it.”
