As for xmlhttprequest not working, I get "DOM object constructor cannot be called as a function"
This basically means xmlhttprequest is a host object which does not want to behave normally. Maybe with some very subtle tricks you can get it to subclass but I recommend not subclassing host objects. I also have a feeling axel means defining a meta object with behaviour for instanceof and new then having every other "class-like" object inherit it as a base class. As an aside if we allow overloading of new and instanceof, can we overload every operator?

More entirely unsubstantiated personal opinion based on a few days experience: Gonzala's https://github.com/Gozala/selfish does this now and with nicer syntax. One subtle point I missed about his approach: instance (member) variables are created in initializers, not as literals, unless you intend to make the variable part of a prototype. This could be stumbling block for Java converts, who expect declarative members. Only bump so far: XMLHttpRequest.apply fails and you can't run XMLHttpRequest.prototype.addEventListener unless you run XMLHttpRequest() on the object. So I could not figure out how to inherit from XMLHttpRequest. jjb _______________________________________________ es-discuss mailing list [email protected] https://mail.mozilla.org/listinfo/es-discuss
