[New-bugs-announce] [issue10889] Fix range slicing and indexing to handle lengths > sys.maxsize

[Nick Coghlan]

New submission from Nick Coghlan <ncoghlan at gmail.com>:

Enhancement to range to correctly handle indexing and slicing when len(x) raises OverflowError.

Note that this enables correct calculation of the length of such ranges via:

        def _range_len(x):
            try:
                length = len(x)
            except OverflowError:
                step = x[1] - x[0]
                length = 1 + ((x[-1] - x[0]) // step)
            return length
