I'm not sure that I understand this code. It makes sure that you get a single
object in memory for the same integer, and not only for Python "small integer
singletons"?
About the -1000..1000 range: if a function leaks more than 1 memory block or
more than 1 reference, there is already something wrong no?
Maybe it's ok to only care of values -1, 0 and 1 :-) My code only cares of
Python small integer singletons.
I have no strong preference between my code or yours. I only care of fixing the
buildbot :-) What do you prefer, Antoine?
