So, "(x=12, y=16).__class__ == type(object())"?

Me, too. I don't fully support this kind of on-the-fly construction as
it is the same for closures. But that might just be my personal feeling
because as such they escape proper testing and type support by IDEs
the other side, it allows ultra-rapid prototyping from which one can
strip down to "traditional development" step by step when needed (using
classes, tests etc.).
This said, what are the reasons for your reservations?
