 Unless I'm missing something, one of these is type str, and the other is
 type bytes, so no ambiguity.


You are missing that the bytes value would get decoded to a str; thus both are str; so ambiguity is possible.

Only if you as the programmer decode it.  Now, I don't understand the
subtleties of Unicode enough to know if Martin has already successfully
addressed this concern in another fashion, but personally I think that
if you as a programmer are comparing funnydecoded-str strings gotten
via a string interface with normal-decoded strings gotten via a bytes
interface, that we could claim that your program has a bug.
