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.
