+    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.

+    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.

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

+
+    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.
