The nested functions do not reference `self` and can be split out, much like `.to_dict` -> `_todict`. Saw this as a chance to add annotations as well. I think this helps illustrate that `.copy` is a noop for anything other than `SchemaBase | dict | list` - which I think might need to be addressed in the future.
10 lines shorter and is no longer constrained to `list` on the assert. May be slightly faster on `python<3.11` which do not have zero-cost exceptions https://docs.python.org/3.11/whatsnew/3.11.html#misc
Remembered a related `ruff` rule [FURB145](https://docs.astral.sh/ruff/rules/slice-copy/). Wouldn't have made this fix, but likely would have led someone there
- Initialize an empty set **once** at origin, rather than creating a new list per iteration - Renamed to `by_ref` in the new private function, to better describe the operation. - No change to public API. - Define a partial `copy` to reduce repetition - Use a genexpr for `args`, to avoid unpacking twice
