{'spam': spam, 'eggs', eggs, **_} = mapping

Actually, I kinda like that, it looks like the side-eye emoji! Or a flounder, but that's a different kettle of fish.
Hm, for PEP 622/634 we looked at this and ended up making it so that this is the default -- you only have to write ``` {'spam': spam, 'eggs': eggs} = mapping ``` and any extra keys are ignored. This is because for the common use case here we want to ignore extra keys, not insist there aren't any.
