Provides an arity-generic version of the liftA2, liftA3... liftAn functions

There's a family of functions in
Control.Applicative
which follow the pattern liftA2, liftA3, etc. Using some
tricks from Richard Eisenberg's thesis we can write them all at once. This
package does exactly that, providing a function (lift) which is an
arity-generic version of the liftAn.
>>> lift (\x y z -> x ++ y ++ z) (Just "a") (Just "b") (Just "c")
Just "abc"

If GHC 8.0 is the earliest GHC you want to support, you can simply state base >= 4.9 as the lower bound on base (which is currently non-reinstallable, and thus can be used as proxy for the GHC version) to prevent the cabal solver from running into such an unsupported configuration.
You can fixup the lower bound via Hackage Metadata Revisions, i.e. via https://hackage.haskell.org/package/arity-generic-liftA-0.1.0.0/arity-generic-liftA.cabal/edit
