LGTM after clean-up. Note that many of the annotations in the README were incorrect, especially with incorrect dimensionality. The dimensionality of the nested array in the return annotation should match the dimensionality of the ndarray.

Thanks @kgryte! Noted — I’ll make sure the README annotations and dimensionality are correct going forward.

[kgryte]

@Orthodox-64 Ideally, our doctest linter would catch when the dimensionality is incorrect. So it seems like there is a bug in our implementation. It correctly errors when dimensionality matches but values differ. Sigh. Another thing to look into.

@kgryte Thanks for the clarification. Understood — this appears to be a doctest linter issue and something we should look into. Appreciate the note.
