No, but so what? The point of the PEP is not to allow arbitrary
Python 2 code to run without modification under Python 3. There's a
reason we broke compatibility, and there's no way we're gonna undo that.

That's not what *I* am trying to do. As far as I'm concerned the aim of
the PEP is to ease bytes interpolation, not to provide some kind of
magical construct that will solve everyone's porting problems.
