GROOVY-9754: Provide a record-like equivalent

How close is this to @Immutable + @POJO? Is there a future path where a record keyword maps to this like trait to @Trait?

[paulk-asert]

Records are indeed somewhat similar to @immutable + @pojo. There are different getter naming conventions, special serialization rules and some other restrictions on records. The goal here would eventually be to create native records with Groovy syntax, so yes a record keyword would be part of that but I don't think that aspect needs to be sorted before alpha-1 and can be done later like trait was added later for @Trait. The AST transform I think is useful enough in it's own right and would allow record-like classes to be created in the meantime until we consider native record support. We just need to not back ourselves into a corner that would disallow native records as a second step.
