[issue47020] float('nan')==math.nan does NOT evaluate to True (as suggested by documentation).

Jelle Zijlstra added the comment: I'm guessing you're referring to https://docs.python.org/3.8/library/math.html#math.nan. The text says explicitly that math.nan is "equivalent" to float("nan"), not that it is equal. This is correct. nan is not equal to itself, because

New submission from Jelle Zijlstra : Inspired by Guido's comment in https://github.com/python/cpython/pull/31834/files#r825352900, I found that there are some places in bytearrayobject.c where we can write to free'd memory if we encounter an object with a sneaky __index__ method: $ cat
