A named import of a re-exported source-phase binding is initialized to the
imported module's ModuleSource object.
esid: sec-source-text-module-record-initialize-environment
info: |
When a module does `import source x from "..."; export { x };`, ParseModule
reclassifies the local re-export to an indirect ExportEntry whose
[[ImportName]] is ~source~. ResolveExport on the re-exporting module returns
a ResolvedBinding Record with [[BindingName]] ~source~ and [[Module]] set to
the source-phase target module.
InitializeEnvironment ( )
7. For each ImportEntry Record in of module.[[ImportEntries]], do
[...]
d. Else,
i. Assert: in.[[ImportName]] is a String.
ii. Let resolution be importedModule.ResolveExport(in.[[ImportName]]).
iii. If resolution is either null or ambiguous, throw a SyntaxError.
iv. If resolution.[[BindingName]] is namespace, then [...]
v. Else if resolution.[[BindingName]] is source, then
1. Let moduleSourceObject be resolution.[[Module]].[[ModuleSource]].
2. If moduleSourceObject is empty, throw a SyntaxError exception.
3. Perform ! env.CreateImmutableBinding(in.[[LocalName]], true).
4. Perform ! env.InitializeBinding(in.[[LocalName]], moduleSourceObject).
The named import `x` is therefore bound directly to the ModuleSource object
of the underlying module, an instance of %AbstractModuleSource%.
