The task

I tried to mix `cattrs.strategies.configure_tagged_union` with a converter configured with `forbid_extra_keys=True`. Ideally this would work out of the box — structuring would remove the `_type` key before structuring the specific union member. Failing that this should be mentioned in the docs.
