Hi. While reading the rich_compare of PyLongObject, I noticed this line: https://hg.python.org/cpython/file/a49737bd6086/Objects/longobject.c#l2785 It increments the ob_ref of the builtin True/False object. Initializing the ob_ref of True/False to one so that they won't be garbage collected if fair enough. Why do we increment it? I don't see the reason behind it, since these two objects should always stay in the memory and never participate the garbage collecting system. Regards. -- 吾輩は猫である。ホームーページはhttp://introo.me。
