+info: |
+  RealmImportValue ( specifierString, exportNameString, callerRealm, evalRealm, evalContext )
+
+    Assert: Type(specifierString) is String.
+    Assert: Type(exportNameString) is String.
+    Assert: callerRealm is a Realm Record.
+    Assert: evalRealm is a Realm Record.
+    Assert: evalContext is an execution context associated to a Realm instance's [[ExecutionContext]].
+    Let innerCapability be ! NewPromiseCapability(%Promise%).
+    Let runningContext be the running execution context.
+    If runningContext is not already suspended, suspend runningContext.
+    Push evalContext onto the execution context stack; evalContext is now the running execution context.
+    Perform ! HostImportModuleDynamically(null, specifierString, innerCapability).
+    Suspend evalContext and remove it from the execution context stack.
+    Resume the context that is now on the top of the execution context stack as the running
+    execution context.
+    Let steps be the steps of an ExportGetter function as described below.
+
+  An ExportGetter function is an anonymous built-in function with a [[ExportNameString]]
+  internal slot. When an ExportGetter function is called with argument exports,
+  it performs the following steps:
+
+    Assert: exports is a module namespace exotic object.
+    Let f be the active function object.
+    Let string be f.[[ExportNameString]].
+    Assert: Type(string) is String.
+    Let hasOwn be ? HasOwnProperty(exports, string).
+    If hasOwn is false, throw a TypeError exception.
