    [...]

    12. For each ImportEntry Record in in module.[[ImportEntries]], do

        a. Let importedModule be ? HostResolveImportedModule(module,

           in.[[ModuleRequest]]).

        b. If in.[[ImportName]] is "*", then

           i. Let namespace be ? GetModuleNamespace(importedModule).

           ii. Perform ! envRec.CreateImmutableBinding(in.[[LocalName]], true).

           iii. Call envRec.InitializeBinding(in.[[LocalName]], namespace).

    1. Assert: module is an instance of a concrete subclass of Module Record.

    2. Let namespace be module.[[Namespace]].

    3. If namespace is undefined, then

       [...]

    4. Return namespace.
