    2. For each Record {[[Module]], [[ExportName]]} r in resolveSet, do:
       a. If module and r.[[Module]] are the same Module Record and
          SameValue(exportName, r.[[ExportName]]) is true, then
          i. Assert: this is a circular import request.
          ii. Return null.
    3. Append the Record {[[Module]]: module, [[ExportName]]: exportName} to resolveSet.

    5. For each ExportEntry Record e in module.[[IndirectExportEntries]], do
       a. If SameValue(exportName, e.[[ExportName]]) is true, then
          i. Assert: module imports a specific binding for this export.
          ii. Let importedModule be ? HostResolveImportedModule(module,
              e.[[ModuleRequest]]).
          iii. Let indirectResolution be ?
