I've recently updated and clarified the draft strawman for simple modules:
http://wiki.ecmascript.org/doku.php?id=strawman:simple_modules
One of the key changes is to the initial environment of modules, addressing the
issue of module name capture pointed out a while back by Jasvir Nagra and Ihab
Awad. The spec now distinguishes externally-loaded modules from internal
modules. Internal modules simply extend the existing environment, like any
other scoping construct. But to prevent external modules from being sensitive
to *all* modules in scope, they are given an initial environment with only the
*local* modules (i.e., the sibling modules declared in the same parent module
as the module-load declaration in question). There are provisions for locally
rebinding a module so that it can be made explicitly visible to an
externally-loaded module.
The strawman now provides a more detailed semantics for the core system. Allen
Wirfs-Brock made the good suggestion that we create a rationale document. I
will be working on that, and I'll send announcement when it's ready. The module
loaders API is not ready yet either, so that'll be another future announcement,
too.
