It works for a non-Sequence generator. Fun fact:

>>> import pandas as pd
>>> pd.Index([1, 2, 3]).reindex(range(1, 3))
(RangeIndex(start=1, stop=3, step=1), array([0, 1]))

Maybe for another PR.

Please remove the following from pyproject.toml

"*category.pyi" = [
  # TODO: remove when pandas-dev/pandas-stubs#1443 is resolved
  "ANN001", "ANN201", "ANN204", "ANN206",
]
