Labels
Bug
Indexing
Related to indexing on series/frames, not to indexes themselves
Nested Data
Data where the values are collections (lists, sets, dicts, objects, etc.).
I have checked that this issue has not already been reported.
I have confirmed this bug exists on the latest version of pandas.
(optional) I have confirmed this bug exists on the master branch of pandas.
Code Sample, a copy-pastable example
Problem description

This applies to both Series and DataFrame.
Full support would be nice.
Expected Output
Output of
pd.show_versions()
