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. (We wrote
it up a little better in the Mapping Patterns section of PEP 635.)
