@davidhewitt I don't understand the stubs signature comparison error, could you have a look?

well I know understand why this is not failing for from_json, we explicitly skip it:

pydantic-core/.mypy-stubtest-allowlist

Line 4 in a3f13c7

pydantic_core._pydantic_core.from_json

@davidhewitt it would be very unfortunate to skip these methods as they're the key pydantic_core api, any ideas how to work around this?

@sydney-runkle I think this is ready.
