> nix-shell can now be used as a #!-interpreter. This allows you to write scripts that dynamically fetch their own dependencies. For example, here is a Haskell script that, when invoked, first downloads GHC and the Haskell packages on which it depends: Wow, that sounds super useful! I'm finding more and more default.nix and shell.nix files scattered through my hard drive, along with wrapper scripts for invoking nix-shells. I can probably replace a lot of these with appropriate shebangs :)
