* Mutations of slices of data should preserve relative indexing as well as cow semantics of slices * Ensure hashes of ranges are uniform to the expected hash for Data * Correct a few mistakes in the slice mutation tests * Update sequence initializations to avoid directly calling mutableCopy which prevents slice offset mismatches * Avoid invalid index slices in creating mirrors * Restore the original Data description * Resetting a slice region should expand the slice to the maximum of the region (not a out of bounds index of the backing buffer) * Remove stray comment and use a stack buffer for sequence appending * Return false when allocations fail in _resizeConditionalAllocationBuffer (not yet in use) * Enumeration of regions of a slice should be limited to the slice range in the case of custom backing (e.g. dispatch_data_t) * adjust assertion warnings for data indexes that are negative
