2.13.2 Runtime Semantics: ClassDefinitionEvaluation
...
30. Set the value of F's [[Fields]] internal slot to fieldRecords.
...
2.14 [[Construct]] ( argumentsList, newTarget)
...
8. If kind is "base", then
...
b. Let result be InitializeInstanceFields(thisArgument, F).
...
2.9 InitializeInstanceFields ( O, constructor )
3. Let fieldRecords be the value of constructor's [[Fields]] internal slot.
4. For each item fieldRecord in order from fieldRecords,
a. If fieldRecord.[[static]] is false, then
i. Perform ? DefineField(O, fieldRecord).
