I am an experienced Flex/AS3 developer and, quite embarassingly, had never coded JS in my life except for a flashy autocomplete form back in 1998. I had hopes for learning JS when Google's closure tools came out, but I still remained suspicious of HTML5 as hype. I can start being less suspicious thanks to this project. Namely: unless it's in python, it's greek to me. The declarative python aspect is like Flex MXML except it actually doesn't suck. As a side note - thanks also to Adobe for messing up everything related to Flex, failing to optimize the Flash runtime for over two years, doing a piss-poor job of now half-open sourcing their Flex package to Apache, etc. etc. to completely and 100% remove any interest I have whatsoever in going back to Flex land now that I have this.
Looks cool but I just don't trust it. Just running through the examples I found a major compiler bug...that was very difficult to debug, given the way pyjs is setup. For now, it seems a great project while it works, but a nightmare if something goes wrong. I have high hopes for it though; once it gets some more dev and a lot more publicity, it will be amazing.
