Edit Question
Title
Body
Many years ago when I didn't know much about object oriented design I heard one guy said something like "How can you write a text editor without polymorphism?" I didn't know much about OOP and so I couldn't judge how wise that though was or ask any specific questions at that time. Now, after many years of software development (mostly C++), I've used polymorphism many times to solve various problems when designing software. Yet I've never created text editors. So I still can't evaluate that guy's idea. Is using polymorphism so essential for implementing a text editor in object-oriented languages and why?
