> Also a note that using a Field would require a serialization/deserialization every time the extension type is used (whereas some core "datatype" based on the `ExtensionType` is parsed once on the way in and serialized once on the way out. I think we could avoid this by doing a `Expr` rewrite early on to "resolve" the extension types into function calls and from then on no additional deserialization would be needed 🤔 Though I may be misunderstanding something -- This is an automated message from the Apache Git Service.
