"The author is against language features implemented as a library."

I don't understand how you can say that, when the entire article is a defense of why they added a bunch of features to Javascript as a library. That is, as opposed to adding those features as part of a new language specification.

I think the actual argument is "as long as you are adding language features as a library, you might as well introduce new syntax for them while you're at it." They present several arguments in defense of this claim.

That's part of it but equally important is the idea of separating language / syntax changes, Objective-J, from the real goal of the library, Cappuccino. The other frameworks mentioned blend the two together, for example you can't get the JavaScript extensions implemented by Prototype without including all of Prototype.

But, with Objective-J you can write for example, some math library that has nothing to do with Cappuccino and not load Cappuccino.
