MultiIndex for obs/var
Can we enable pd.MultiIndex for obs/var?
I assume that should be implemented somewhere here? Would that be doable?
What do you expect to work which doesn’t? Some specific examples would be nice. Is this about indexing using a pandas.MultiIndex instance and that doesn’t behave as expected or do you want to index with, say, a list of tuples and that doesn’t work as expected? What does “doesn’t work as expected” mean in this case? Is there an error or (worse) wrong behavior?
At a glance, passing in a pandas.MultiIndex instance like ad[pd.MultiIndex(...), :] should probably work? What’s a MultiIndex’s dtype?
