I am unclear from this proposal. What would happen if I declared
the same module twice? Would it reopen the module and add the extra
declarations?
The simple modules proposal makes it an error to export twice. This is
a bit implicit in
http://wiki.ecmascript.org/doku.php?id=strawman:simple_modules#export_declarations
That you get an error on duplicate export is a good point to make
explicitly.
Not sure if you meant Dmitry's "export *;" idea. That would export
everything, but again if something was already exported, then there
was already a const binding in the module's exports and you'd get an
error.

I wonder if you considered having an export list, rather than

to see/document the public API of a module. You could at the

Yes, this is a good point. We chose inline-export for
convenience, but I don't see any reason not to allow both.
+1 on an export form that takes a list of already-declared names.
Besides, the variation with
export all; // or export "all";
can be considered. It can be useful for debug.
Debugging is good.
This is a minor point, but rather than all, we'd use * instead, to
mirror import M.* or M.{*} or import * from M; whatever it ends up
being.
Or, simply -- to omit export statement. Thus, if there will be no
local export statement for some function, it means that all
functions/properties are exported. Although, it breaks the first
design where by default methods are private for a module.
Sorry, the idea of implicit everything-exported is a footgun. Just
say no.
Excluding:
export all except [intrinsic, builder]; // if we don't want to
write 20 of 22 methods to be exported
This is overdesign. By far the most common case is explicit export
of a select list of API functions and consts.
