Subject: As we’re preparing to release v2, we want to delete the experimental
 editions of the Builder and Value annotations… but in case you install lombok
 v2 into eclipse but use an older lombok as dep in your project, we still do
 want to process the old annotations. Had to stringly-type a few things to
 make that happen, but, works now.
