 // The original function Tensor.subscriptIndexPath() is not marked as @differentiable. As a result, no explicit differentiable witness is generated for it.
 // However, the witness is generated as a side effect of providing a derivative via  @derivative(of: subscriptIndexPath) on _vjpSubscriptIndexPath.
