Being able to specify the shape of arrays will really help me when typing numeric code. I recently wrote:

    RotationMatrix_3x3 = npt.NDArray
    TranslationVector_3x1 = npt.NDArray

and that felt kind of gross. But for numpy heavy it is really useful to know and specify the size of matrices. Will switch over the minute 3.11 lands
