```
> nix repl
nix-repl> pkgs = import ./nixpkgs.nix {}

nix-repl> drvs = import (pkgs.fetchFromGitHub {
  owner = "justinwoo";
  repo = "easy-dhall-nix";
  rev = # some REV
  sha256 = # some SHA
}) { inherit pkgs; }

nix-repl> drvs.dhall-simple
«derivation /nix/store/qz29jbplpmlvsbmq05084dh1fbs8sl0h-dhall-simple.drv»
