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?
This is not in 8.2, it may be in 8.4.
(The Status page is confusing: it has a header for it, but the text says: "...but no OverloadedRecordFields extension or...". Perhaps the header should be changed to "Progress on overloaded record fields"?)
