set and are re-exposed with a reduced dependency closure for convenience.
(see `justStaticExecutables` or `separateBinOutput` below)

The `haskellPackages` set includes at least one version of every package from
Hackage as well as some manually injected packages. This amounts to a lot of
packages, so it is hidden from `nix-env -qa` by default for performance reasons.
You can still list all packages in the set like this:
The `haskellPackages` set includes at least one version of every package from [Hackage](https://hackage.haskell.org/) as well as some manually injected packages.
Haskell packages can be searched on [search.nixos.org](https://search.nixos.org/packages?query=haskellPackages) or listed on the command line with [`nix-instantiate`](https://nixos.org/manual/nix/stable/command-ref/nix-instantiate):

```console
$ nix-env -f '<nixpkgs>' -qaP -A haskellPackages
haskellPackages.a50 a50-0.5
haskellPackages.AAI AAI-0.2.0.1
haskellPackages.aasam aasam-0.2.0.0

Also, the `haskellPackages` set is included on [search.nixos.org].

The attribute names in `haskellPackages` always correspond with their name on
Hackage. Since Hackage allows names that are not valid Nix without escaping,
