I'd probably use itertools.count() or the uuid module to generate globally unique dimension names... something like ```python class UnnamedDimensions: def __init__(self): self.dimension_names = (f"unnamed_dim{number}" for number in itertools.count())

def __call__(self, n):
    return list(itertools.islice(dimension_names, None, n))

unnamed_dimensions = _UnnamedDimensions() or using `uuid` (probably overkill):python def unnamed_dimensions(n): return [uuid.uuid4() for _ in range(n)] you'd use it like this:python d1 = xr.DataArray(data=[1, 2], dims=unnamed_dimensions(1)) d2 = xr.DataArray(data=[[1, 2]], dims=unnamed_dimensions(2)) ``` which would make "unnamed" a bit more explicit.

Edit: that's probably not so different from what you meant with d1_i
