[Haskell-cafe] OverloadedRecordFields in GHC 8.2.1-rc2

Hi, I'm trying out the GHC 8.2.1 release candidate [1], added 'OverloadedRecordFields' and I get an error saying it's an 'Unsupported Extension'. Am I doing something wrong? Thanks! -deech [1] https://mail.haskell.org/pipermail/ghc-devs/2017-May/014197.html
