GeneratorMethod :
* PropertyName ( StrictFormalParameters ) { GeneratorBody }
1. Let propKey be the result of evaluating PropertyName.
2. ReturnIfAbrupt(propKey).
3. If the function code for this GeneratorMethod is strict mode code,
let strict be true. Otherwise let strict be false.
4. Let scope be the running execution context's LexicalEnvironment.
5. Let closure be GeneratorFunctionCreate(Method,
StrictFormalParameters, GeneratorBody, scope, strict).
[...]
9.2.1 [[Call]] ( thisArgument, argumentsList)
[...]
7. Let result be OrdinaryCallEvaluateBody(F, argumentsList).
[...]
9.2.1.3 OrdinaryCallEvaluateBody ( F, argumentsList )
1. Let status be FunctionDeclarationInstantiation(F, argumentsList).
[...]
9.2.12 FunctionDeclarationInstantiation(func, argumentsList)
[...]
23. Let iteratorRecord be Record {[[iterator]]:
CreateListIterator(argumentsList), [[done]]: false}.
24. If hasDuplicates is true, then
[...]
25. Else,
b. Let formalStatus be IteratorBindingInitialization for formals with
iteratorRecord and env as arguments.
[...]
13.3.3.6 Runtime Semantics: IteratorBindingInitialization
ArrayBindingPattern : [ Elisionopt BindingRestElement ]
1. If Elision is present, then
a. Let status be the result of performing
IteratorDestructuringAssignmentEvaluation of Elision with
iteratorRecord as the argument.
b. ReturnIfAbrupt(status).
2. Return the result of performing IteratorBindingInitialization for
BindingRestElement with iteratorRecord and environment as arguments.
