[Python-Dev] Re: When to remove BytesWarning?

If I recall, it was str(bytes) warning that flagged in a few places and was missing a .decode() call or similar.

It seems like the bytes== warnings could be implemented in a type checker such as mypy, if it doesn't already do this. Assuming you have correct type coverage/inference on your project, you could potentially catch this at static analysis time rather than runtime.

There were several bugs like sep=='/' (where sep can be bytes) in the stdlib. These cases were not covered by tests, so they were fixed only in 3.3 or even later. I hope all such bugs are already fixed, but I cannot guarantee. And there were bugs with str(bytes) too.
