Prototype systems are great. I use them all the time, even in other languages. Extending prototypes of existing objects is amazing and powerful, and can be used for some beautiful data structures.

> Extending prototypes of existing objects is amazing and powerful What can you do with it that you can't do in class-based OO languages?

  Nothing you couldn't do in assembly. Just easier and more elegant.

    Could you give an example? I'm curious, because I've never found any difficulties subclassing in a class-based language. What extra does prototype-based subclassing give me?
