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.

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.

1. If iteratorRecord.[[done]] is false, then
a. Let next be IteratorStep(iteratorRecord.[[iterator]]).

e. Else,
i. Let v be IteratorValue(next).

4. Return the result of performing BindingInitialization of BindingPattern
with v and environment as the arguments.
