The correct solution is to write a DOM interface for Python and start distributing browsers with Python VMs. Python's not a perfect language but it's much better than JavaScript. There are acceptable alternatives besides Python too, but that would be my favorite. I don't see why we need to invent a whole new scripting language for client-side execution on the web, the problems really aren't that special. I know the history of JavaScript and I'm not saying it didn't serve a purpose for a time, but that time has passed; it's time to move on and put in a big boy programming language.
