Mark, I see how it's possible to reinterpret data in memory but it seems like the dataspace for the dataset is fixed to how it was created. You can only hyperslab it but not write using a reinterpretation of its shape. I can't find how the API allows that at least. I'm hoping there is something I missed or a tricky way around it. I wouldn't be surprised if there wasn't though since it breaks encapsulation of the dataset's memory layout, although that would be sort of academic since we need to write things knowing that datasets are row-major.
