View source for JavaScript:JS3 Requirements

* Standardized hybrid information flow security model
* AST binary syntax as over-the-wire standard (self-verifying? implicit flows?)
* AST reflection
* Quotations
* Hygienic macros
* Safe, scalable concurrency
* "E5X"
** E4X's query and path operators rationalized for all types
** XDuce or similar extensions to the JS2/ES4 type system
* Changes to the core language, in particular to error handling rules, to make it easier to add new syntax in future versions of the language (JS n, where n > 3) without scripts using those languages breaking in earlier browsers (JS 3..n-1)
** This requires lexical and syntactic grammar extensibility, not just error handling as in [http://www.whatwg.org/specs/web-apps/current-work/#html5 HTML5]
* BigInt and other Big numeric types (int64/uint64?), and pragma support to use them for numeric literals and operators by default
