> Web developers don't have the option of getting browsers to add new code every time they want to add a complex new feature to their app

We lack a mechanism for picking sane new features. Browsers add new stuff all the time. Most of it is horrible. [Say] Adding a js assembly has to be the most stuborn way of tollerating new langages. you may do it, as long as the new lang is js!? You can have butter as long as it is yogurt.

I dont like pyton. I wouldn't be upset by <script type="pyton"> add some of the dom tools to it and people will have a ton of fun. Might even be useful.
