This error occurs a few times. BaseOffset does not have this attribute but almost all(?) sub-classes of BaseOffset have this attribute.

Combined these two lines to not assign a new type to result

These operators are not "perfect" but they might be good enough for now. Based on the current annotations, __add__(self: Year, other: Second) is declared to return a Year but it actually returns Second

@twoertwein can you merge main |

@jbrockmendel rebased and green |

i think this is a perf optimization for dtype == self.dtype that might no longer be necessary; i think we do this in PeriodDtype.eq now.

Should probably be done in a separate PR.

@twoertwein status here? |
I think it should be ready. The open two comments would require non-typing changes, which I would like to avoid in this PR. |

thanks @twoertwein |

hmm maybe should have rebase first, oh well, let's see |
