    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.

    SingleNameBinding : BindingIdentifier Initializeropt

    [...]
    6. If Initializer is present and v is undefined, then
       [...]
       d. If IsAnonymousFunctionDefinition(Initializer) is true, then
          i. Let hasNameProperty be HasOwnProperty(v, "name").
          ii. ReturnIfAbrupt(hasNameProperty).
          iii. If hasNameProperty is false, perform SetFunctionName(v,
               bindingId).
