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.
