Throws a nested hierarchy of SuppressedErrors if multiple errors were thrown during evaluation of subsequent statements following 'using'
and/or from disposal.
info: |
DisposeResources ( disposeCapability, completion )
1. For each resource of disposeCapability.[[DisposableResourceStack]], in reverse list order, do
a. Let result be Dispose(resource.[[ResourceValue]], resource.[[Hint]], resource.[[DisposeMethod]]).
b. If result.[[Type]] is throw, then
i. If completion.[[Type]] is throw, then
1. Set result to result.[[Value]].
2. Let suppressed be completion.[[Value]].
3. Let error be a newly created SuppressedError object.
4. Perform ! CreateNonEnumerableDataPropertyOrThrow(error, "error", result).
5. Perform ! CreateNonEnumerableDataPropertyOrThrow(error, "suppressed", suppressed).
6. Set completion to ThrowCompletion(error).
ii. Else,
1. Set completion to result.
2. Return completion.
Dispose ( V, hint, method )
1. If method is undefined, let result be undefined.
2. Else, let result be ? Call(method, V).
3. If hint is async-dispose, then
a. Perform ? Await(result).
4. Return undefined.
