Description
es6 modules can export module elements without declaration.
import foo from 'foo';
export {foo}
Namespaces are not.
import foo from 'foo';
namespace NS {
export {foo} // not support syntax
export var foo = foo; // invalid
var bar = foo;
export var foo = bar; // too redundant
}
Namespaces should support non-declaration export.
