[~] [@With](https://projectlombok.org/features/With)

Other todos:
 - [x] Generic classes
 - [x] Actually run compiled code 
 - [x] Don't generate members that already exist (if having a duplicate is a problem)
 - [x] Gradle integration (as subplugin or just a way to enable lombok support)
 - [x] Gradle plugin integration test
 - [x] Maven integration (as subplugin or just a way to enable lombok support)
 - [x] Nullability from annotations. Check if it is inherited from variable definition
