Serhiy Storchaka added the comment: Nice! This is an example of good microoptimization. The performance gain is tiny (although measurable), but the cost is virtually zero: it does not increase code complexity and does not have side effects. -- resolution: -> fixed stage: patch

[issue36062] move index normalization from list_slice() to PyList_GetSlice()

New submission from Sergey Fedoseev : list_slice() is used by PyList_GetSlice(), list_subscript() and for list copying. In list_subscript() slice indices are already normalized with PySlice_AdjustIndices(), so slice normalization currently performed in list_slice() is only needed for
