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.

9.2.1.3 OrdinaryCallEvaluateBody ( F, argumentsList )

b. Let formalStatus be IteratorBindingInitialization for formals with
iteratorRecord and env as arguments.

i. Return the result of performing BindingInitialization of
BindingPattern with A and environment as the arguments.
