    Yes. I realise that I would have to pre-allocate the array and make sure that neither the array (length), nor the scalar (at all) is mutated.

    I'd probably set them read-only using Internals::SetReadOnly() to assist in ensuring that. I realise that probably isn't foolproof. But it's just and experiment.
