Imho, this is not equivalent to re-introducing automatic type conversion between binary/unicode, it is adding a specific convenience function for explicitly asking for ASCII encoding. It is not explicit, it is implicit - whether or not the resulting string assumes ASCII compatibility or not depends on whether you pass a binary value (no assumption) or a string value (assumes ASCII compatibility).

Nick, I don't understand what you are saying here. Are you saying that the result of b'%s' % var may be either a bytes object or a str object? Because that would be wrong -- it would always be a bytes object.
