+description: Private methods are installed "when super returns" and no earlier (call in constructor) (field definitions in a class declaration)
+esid: prod-FieldDefinition
+features: [class-methods-private, class]
+flags: [generated]
+info: |
+    SuperCall: super Arguments
+      1. Let newTarget be GetNewTarget().
+      2. If newTarget is undefined, throw a ReferenceError exception.
+      3. Let func be ? GetSuperConstructor().
+      4. Let argList be ArgumentListEvaluation of Arguments.
+      5. ReturnIfAbrupt(argList).
+      6. Let result be ? Construct(func, argList, newTarget).
+      7. Let thisER be GetThisEnvironment( ).
+      8. Let F be thisER.[[FunctionObject]].
+      9. Assert: F is an ECMAScript function object.
+      10. Perform ? InitializeInstanceElements(result, F).
+
+    EDITOR'S NOTE:
+      Private fields are added to the object one by one, interspersed with
+      evaluation of the initializers, following the construction of the
+      receiver. These semantics allow for a later initializer to refer to
+      a previous private field.
