    1. Let rhs be the result of evaluating Initializer.
 | 
						|
    2. Let value be GetValue(rhs).
 |

    3. ReturnIfAbrupt(value).
 | 
						|
    4. Let env be the running execution context's LexicalEnvironment.
 | 
						|
    5. Return the result of performing BindingInitialization for BindingPattern
 | 
						|
       using value and env as the arguments.
