  RS: Evaluation
    UsingDeclaration : using BindingList ;

    1. Perform ? BindingEvaluation of BindingList with argument sync-dispose.
    2. Return empty.

  RS: BindingEvaluation
    BindingList : BindingList , LexicalBinding

    1. Perform ? BindingEvaluation of BindingList with argument hint.
    2. Perform ? BindingEvaluation of LexicalBinding with argument hint.
    3. Return unused.

    LexicalBinding : BindingIdentifier Initializer

    ...
    5. Return ? InitializeReferencedBinding(lhs, value, hint).

  InitializeReferencedBinding ( V, W )

  ...
  4. Return ? base.InitializeBinding(V.[[ReferencedName]], W).

  InitializeBinding ( N, V, hint )

  ...
  2. If hint is not normal, perform ? AddDisposableResource(envRec.[[DisposeCapability]], V, hint).

  AddDisposableResource ( disposeCapability, V, hint [, method ] )

  1. If method is not present then,
    a. If V is either null or undefined and hint is sync-dispose, then
      i. Return unused.
    b. Let resource be ? CreateDisposableResource(V, hint).
  3. Else,
