Uhm, just a couple of extra question about that page if/when you have time:
1. string and boolean are mentioned, but nowhere in your `struct.js` prolyfill code. Will string and boolean be accepted? 2. `Object` and `Any` are mentioned, but exported as object and any in your `struct.js` prolyfill example. W 3. Which is the right way? The reason I am asking is to be able to create code that does absolutely nothing (for performance reason) but will look like the real thing so I can start experimenting with static structures and possibly a develop VS production version of an ES3 to ES5 compatible polyfill since I believe your code won't run anywhere except in SpiderMonkey (which is OK but it's not suitable for a lightweight migration to "structure like" logic) Thanks.
