To build a package, say [lens][], from a Stackage snapshot, say
[lts-13.28][], you could run:
```bash
nix build '(with import <nixpkgs> (import (builtins.fetchTarball "https://github.com/input-output-hk/haskell.nix/archive/master.tar.gz")).nixpkgsArgs; haskell-nix.snapshots."lts-13.28").lens.components.library'

build plan for the [lens-4.17.1][] package.
