    Static Semantics: Early Errors
    Script : ScriptBody
      1. Let names be an empty List.
      2. If Script is parsed directly from PerformEval,
          a. Let env be the running execution context's PrivateNameEnvironment.
          b. Repeat while env is not null,
              i. For each binding named N in env,
                  1. If names does not contain N, append N to names.
              ii. Let env be env's outer environment reference.
      3. If AllPrivateNamesValid of ScriptBody with the argument names is false, throw a SyntaxError exception.
