Look into using Pydantic under the hood

[ericpan64]

Pydantic already solves many of the existing problems with #20 -- the main goal of the Pydian validation would be to make it easier to express some of the different rules and error cases (e.g. make it easier to slightly modify an existing model / set of rules)

E.g.

• https://docs.pydantic.dev/latest/#pydantic-examples
• https://docs.pydantic.dev/dev/errors/validation_errors

Could we get the best of both -- e.g. use Pydantic under the hood and make data models interoperable? Worth investigating further!

A key use-case could be handling heavily-nested structures, and making it easier to express code and reduce the need for a bunch of custom middle classes
