There was a problem hiding this comment.
Re letting callers decide if this is necessary - I assume this is for general cleanliness and to avoid the overhead of a function call if not necessary?
…in the process of being built Do not rely on `__pydantic_validator__`, an attribute which is set only when the class is fully built. Because we check for this condition during schema building, we end up considering the class as a stdlib dataclass. As a consequence, the deepcopy logic of `FieldInfo` instances was tweaked, as in some tests, the deep copy would fail. Instead, make a shallow copy of every `FieldInfo` instance, this is enough (the same thing is done in `collect_model_fields` for Pydantic models, we make a shallow copy of the parent fields).
Let callers be responsible for checking if using docstrings is necessary.
