- The top-level `lib` must be used in the master and 21.05 branch over its alias `stdenv.lib` as it now causes evaluation errors when aliases are disabled which is the case for ofborg.

  `lib` is unrelated to `stdenv`, and so `stdenv.lib` should only be used as a convenience alias when developing locally to avoid having to modify the function inputs just to test something out.
