   Use this package instead of <http://hackage.haskell.org/package/microlens 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 (<http://hackage.haskell.org/package/array array>, <http://hackage.haskell.org/package/bytestring bytestring>, <http://hackage.haskell.org/package/containers containers>, <http://hackage.haskell.org/package/transfromers transformers>).
