Re: [ANNOUNCE] GHC 9.2.1-rc1 now available

Sorry, I was unclear. I want it re-exported from Data.Tuple, so I don't need to import ghc-prim:GHC.Tuple. I proposed this on the libraries list last year, and the two people who responded agreed. On Sun, Aug 22, 2021, 9:37 PM Viktor Dukhovni wrote:

One more question: is Solo exported from Data.Tuple yet, or do we still have to depend on ghc-prim and import it from GHC.Magic? It would be really nice to have that fixed by release, and it's so tiny.

The GHC.Tuple modules (from ghc-prim) are identical in the HEAD and ghc-9.2 branches. With HEAD I see:
