* feat: pydantic dataclasses support built-in ones closes #744 * feat: improve dataclass typing * feat: add support for nested dataclasses closes #1743 * feat: support dataclass schema with nested dataclasses * refactor: remove `_dataclass_with_validation` function * docs: add docstring for `make_dataclass_validator` * refactor: rename DataclassType into Dataclass The name `DataclassType` was missleading as it's not a `Type` per say. * refactor: change global `dataclass` import to local pydantic import time was improved in https://github.com/samuelcolvin/pydantic/pull/1132 by keeping `dataclass` import local. So let's keep it that way! * test: add extra nested case with BaseModel * chore: s/pydantic/_pydantic_/g * docs: add some documentation
