[New-bugs-announce] [issue16722] __index__() overrides __bytes__() when bytes() is called

[Руслан Ижбулатов]

New submission from Руслан Ижбулатов:

If a class implements both __index__() and __bytes__(), the built-in bytes() constructor uses __index__() in place of __bytes__(), including the assumption that __index__() returns a bytes object.

Attaching a simple example (leads to overflow when big integer is casted to bytes).
