    27. For each ClassElement e in order from elements
      ...
      d. Append to fieldRecords the elements of fields.
    ...
    33. Let result be InitializeStaticFields(F).
    ...

    [[Construct]] ( argumentsList, newTarget)

    8. If kind is "base", then
      a. Perform OrdinaryCallBindThis(F, calleeContext, thisArgument).
      b. Let result be InitializeInstanceFields(thisArgument, F).
      ...
    ...
    11. Let result be OrdinaryCallEvaluateBody(F, argumentsList).
