[issue23124] Incorrect Integer saving

[Adam Carruthers]

New submission from Adam Carruthers:

255 is 255 -> True           (255).bit_length() -> 8
256 is 256 -> True           (256).bit_length() -> 9
257 is 257 -> False          (257).bit_length() -> 9
^
Will show True if you do it exactly like this because of a quirk.
a = 257
b = 257
a is b -> False

I think you don't want to map variables to integers direct unless they are at or under 8 bits in length.
