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.
