libghc-microlens-ghc-dev 0.4.8.0-1build1 (amd64 binary) in ubuntu bionic

 Use this package instead of microlens if you don't mind depending on
 all dependencies here – Lens.Micro.GHC reexports everything from
 Lens.Micro and additionally provides orphan instances of microlens
 classes for packages coming with GHC (array, bytestring, containers,
 transformers).
 .
 The minor and major versions of microlens-ghc are incremented
 whenever the minor and major versions of microlens are incremented,
 so you can depend on the exact version of microlens-ghc without
 specifying the version of microlens you need.
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
