And there is a very good reason for accepting None in the second parameter in slice notation as there is no value for '-0' to represent the end of the region being sliced, and None meaning 'default' fills that need most effectively. Surely the right fix is as Barry noted, to handle None correctly within this function?

This would be a false message, as, as my report demonstrated, slice
indices *can* be None. And there is a very good reason for accepting
None in the second parameter in slice notation as there is no value for
'-0' to represent the end of the region being sliced, and None meaning
'default' fills that need most effectively.

Surely the right fix is as Barry noted, to handle None correctly within
this function?
