esid: prod-DestructuringAssignmentTarget
desc: >
  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 initializer.
info: |
  Syntax

  AssignmentPattern : ObjectAssignmentPattern
  ObjectAssignmentPattern : { AssignmentPropertyList }
  AssignmentPropertyList : AssignmentProperty
  AssignmentProperty : PropertyName : AssignmentElement
  AssignmentElement : DestructuringAssignmentTarget Initializer_opt
  DestructuringAssignmentTarget : LeftHandSideExpression

  Static Semantics: Early Errors

  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.

  Runtime Semantics: DestructuringAssignmentEvaluation
  ObjectAssignmentPattern : { AssignmentPropertyList }

  1. Perform ? RequireObjectCoercible(value).
  2. Perform ? PropertyDestructuringAssignmentEvaluation for AssignmentPropertyList using value as the argument.
  3. Return NormalCompletion(empty).

  Runtime Semantics: PropertyDestructuringAssignmentEvaluation

  AssignmentProperty : PropertyName : AssignmentElement

  1. Let name be the result of evaluating PropertyName.
  2. ReturnIfAbrupt(name).
  3. Perform ? KeyedDestructuringAssignmentEvaluation of AssignmentElement with value and name as the arguments.
  4. Return a new List containing name.

  Runtime Semantics: KeyedDestructuringAssignmentEvaluation

  AssignmentElement : DestructuringAssignmentTarget Initializer

  1. If DestructuringAssignmentTarget is neither an ObjectLiteral nor an ArrayLiteral, then
    a. Let lref be the result of evaluating DestructuringAssignmentTarget.
