VariableDeclaration : BindingPattern Initializer
1. Let rhs be the result of evaluating Initializer.
2. Let rval be GetValue(rhs).
3. ReturnIfAbrupt(rval).
4. Return the result of performing BindingInitialization for
BindingPattern passing rval and undefined as arguments.
ArrayAssignmentPattern : [ AssignmentElementList ]
[...]
5. If iteratorRecord.[[done]] is false, return IteratorClose(iterator, result).
