Pointers in Python

IINM the reference implementation has a cache for small integers. I wonder what happens if you try the ctypes example in the article with one of the cached integers.

Nothing happens with the cache. According to the article you can't use a Python int, instead you have to use a ctypes.c_int and those are not cached.

This is an excellent question with a generally fun answer, at least in python 2.

I found these offhand, but I'm pretty sure I saw this trick earlier than 2017.
