    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.

    13.3.3.6 Runtime Semantics: IteratorBindingInitialization
    BindingRestElement : ... BindingIdentifier
    1. Let lhs be ResolveBinding(StringValue of BindingIdentifier,
       environment).
    2. ReturnIfAbrupt(lhs). 3. Let A be ArrayCreate(0). 4. Let n=0. 5. Repeat,
       [...]
       b. If iteratorRecord.[[done]] is true, then
          i. If environment is undefined, return PutValue(lhs, A).
          ii. Return InitializeReferencedBinding(lhs, A).
