This isn't quite true, but I will admit that the only way I know how to do it is somewhat on the arcane side ;)

try: double_width = 2*(sys.maxint+1)**2-1 slice(None).indices(double_width) pyssize_t_max = double_width # ssize_t twice as wide as long except OverflowError: pyssize_t_max = sys.maxint # ssize_t same width as long

It might make more sense to just include a "sys.maxindex" to parallel sys.maxint (even though both are technically misnomers, leaving out the 'native' bit).

Cheers, Nick.
