b. Else,
Let status be the result of performing PropertyDefinitionEvaluation for
m with arguments F and false.

MethodDefinition : PropertyName ( StrictFormalParameters ) { FunctionBody }
[...]
6. Let closure be FunctionCreate(kind, StrictFormalParameters, FunctionBody,
scope, strict). If functionPrototype was passed as a parameter then pass its
value as the functionPrototype optional argument of FunctionCreate.

iteratorRecord and env as arguments.

Runtime Semantics: IteratorBindingInitialization
SingleNameBinding : BindingIdentifier Initializer_opt
1. Let bindingId be StringValue of BindingIdentifier.
2. Let lhs be ? ResolveBinding(bindingId, environment).
3. If iteratorRecord.[[Done]] is false, then
a. Let next be IteratorStep(iteratorRecord).
b. If next is an abrupt completion, set iteratorRecord.[[Done]] to true.
c. ReturnIfAbrupt(next).
d. If next is false, set iteratorRecord.[[Done]] to true.
e. Else,
i. Let v be IteratorValue(next).
ii. If v is an abrupt completion, set iteratorRecord.[[Done]] to true.
iii. ReturnIfAbrupt(v).
