The DestructuringAssignmentTarget of an AssignmentElement can extend to LHSExpressions if
it is neither an ObjectLiteral nor an ArrayLiteral and its AssignmentTargetTyp is simple.
Using MemberExpression (ObjLiteral + identifier) with activated initializer.

DestructuringAssignmentTarget : LeftHandSideExpression
- It is a Syntax Error if LeftHandSideExpression is either an ObjectLiteral or an ArrayLiteral and if LeftHandSideExpression is not covering an AssignmentPattern.
- It is a Syntax Error if LeftHandSideExpression is neither an ObjectLiteral nor an ArrayLiteral and AssignmentTargetType(LeftHandSideExpression) is not simple.

ArrayAssignmentPattern : [ AssignmentElementList ]
1. Let iteratorRecord be ? GetIterator(value).

3. If iteratorRecord.[[Done]] is false, return ? IteratorClose(iteratorRecord, result).
4. Return result.

1. If DestructuringAssignmentTarget is neither an ObjectLiteral nor an ArrayLiteral, then
