It seems the consequences of PEP 0448 weren't really thought through. :-/ (And BTW why isn't it in "What's new in Python 3.5"? I know there is a file with full details, but I guess this really should be notable enough.)

    {0:1, **{0:2}, 0:3, 0:4}

Do you know what is the value of that dict? And does it make sense to you? It surely doesn't make sense to me (though I understand the implementation). I know things are really subtle and even Guido gets it wrong (https://bugs.python.org/msg234413), even without PEP 0448, but this particular instance is horrible.

ValueError would be perfect, I'd be ok with 4, I'd shrug on 1, I'd frown on 2, but I _scream_ on 3. Please fix this until it's too late and fictional "backward compatibility" starts to freeze the wrong behaviour.
