Raymond Hettinger added the comment: I agree with the other commenters and recommend this be closed. There doesn't seem to be a a useful issue here. It seems more like a pedantic twisting of words that ignores how Python works (i.e. that you can specify a specific class to inherit from and that it is possible to either shadow or alter builtins). I don't see any magic here beyond changing a variable name to refer to a new object while previous references (or builtin references) to that name continue to refer to old object. ---------- nosy: +rhettinger _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue31283> _______________________________________
