Implement the "Derive Lift instances for data types in template-haskell" proposal
Back in September 2015, I proposed using the
DeriveLift extension to, well, derive
Lift instance for data types in the
template-haskell library. The proposal was well received, but I was unable to implement it at the time due to
DeriveLift's newness (having only been introduced in GHC 8.0). Now that GHC 8.0 is the oldest version of GHC that we support bootstrapping with, this is no longer an obstacle.
