Constructors don't work for DOM elements

[ghik]

I don't see a reason why DOM elements like HTMLElement are represented by classes and not traits or abstract classes.

Currently the compiler does not protect us from trying to create HTML elements with plain constructor but it won't work in runtime.

Those for which creation at runtime is not permitted by the spec should indeed be abstract classes.

Any reason to use abstract class over trait? We tend to use trait in things like AudioAPI, WebGL, etc., so it would be more consistent if possible to use trait, I'd say.

[sjrd]

Yes, you can do x.isInstanceOf[dom.HTMLElement] if HTMLElement is a class. It translates to x instanceof HTMLElement in JS. You can't do that if it's a trait.

Gotcha, okay, I'll go with that, then.
