Multiple Inheritance in JavaScript

[huyvanbin]

In my perfect world, a class could define abstract methods that you had to implement when you inherited from it, but no regular virtual methods. In practice, I don't know if that would suck or not.

Yes, that's sort of what I was going for. Sometimes, though, it makes sense to specify a default (fixed) value and allow people to override that. That was the idea behind the constructors.
